HTPC Build Help Needed

To be fair, with (at least lower-end) Llano, I'm a little concerned you could run into CPU power limitations, especially with emulation as part of the game, Tom'sHardware for example only rates the Llano 3500 on par, if not a bit slower, than a Athlon/Phenom x4 at 1.5Ghz. Now from experience, a modern Athlon/Phenom x3 chip@3Ghz will run virtually anything out there reasonably well at about 50-60%, even 10bit H264 with karaoke subs, I'm just a little concerned that may leave Llano borderline depending on how wide your media tastes run, which chip you went for, and what other uses you decide to throw at the system, although it's no doubt most media will run fine, indeed the vast majority should happily handle via hardware decoding instead of relying on the CPU, but by comparison the CPU is the weak link.

If you do decide to go Llano, rather than going for the weaker 3500 (which I have seen people comment elsewhere struggles with CPU decoding at times), I'd fully recommend you spend the extra to get the 3870k which has an additional core and higher clock speeds (the GPU is marginally stronger but thats not the focus here), which will really give the system a boost moving forward, from a few reviews I've gone through, the reviewers seem far more comfortable with the power afforded by the chip in terms of CPU, as its approaching Sandybridge with the additional core and higher clocks (although as per Llano across the board, it's GPU is faster than Intels). Although the 3870K is quite a bit more than the 3500, the performance improvement for your range of needs seems worth it (3 to 4 core, 2.4Ghz to 3Ghz, faster onboard GPU, plus the K is unlocked and may net a moderate overclock. Hothardware put the 3870k, overclocked to 3.5Ghz, in the PhenomX4 980 potency range, which sounds much more robust).

Personally, especially as it seems you might need more oomph at times if emulation is of interest (will you be looking at Wii?), I'd feel happier recommending you the higher performing platform, be it Sandybridge, or the new, more expensive Llano.

In desktop terms, the 5870m is somewhere between a 5750 and 5770 :) The Llano onboard chips are not this fast, they have half the shaders of a 5770 and a lower core speed. A Sandybridge/decent GPU combo would be the fastest option, but obviously will cost that much more. If you were to go for the Llano, you could pretty much take my i3 spec above, drop the I3, 6670 and motherboard, and replace with a FM1 motherboard and 3870k, and take a look at a GPU once you've evaluated the performance of the onboard. Without the GPU this would be cheaper, as there seem to be some decent value FM1 motherboards, and you're dropping the cost of the GPU.

Ah if you are running emulators then I would have thought a Llano A8 would be ok on its own. More than that and you are looking at a discrete card. Something like a 6670 upwards depending on what resolution/quality you want.

edit: The 3870K has an extra core?

edit2: Oh you mean over a 3500? Yeah I would certainly go for an A8 really or an i3 with discrete card.

Yeah sorry if that wasn't clear. The 3500 which I keep seeing recommended is 3 core, 2.4Ghz per core, whereas the 3870K is multiunlocked, 4 core and 3Ghz stock.

Sandybridge is even stronger, but if the OP opts for Llano I think the 3870K seems to be much more appropriate for the range of interests and usages the OP has shown/suggested; I think the 3500 might be a bit too anaemic; Llano being a low power platform at the end of the day.
 
Its just so confusing when been out of pc building for a few years. Nintendo wii is another emulator i'm messing around with at the moment. Like i said its emulation i'm more instrested in than overhall pc gaming. My laptop runs my emulation fine but its starting to take to much hd space so moving it to mix with a htpc seems the right choice as i get to use it on big screen.

My laptop spec is the following if this helps on the emulation part.

Intel® Core™ i7 Processor 620M/820QM/720QM :1.6 GHz (not sandybridge)
DDR3 1066/1333 MHz 8GB
ATI Mobility™ Radeon® HD 5870, 1G GDDR5 VRAM

My a6 3500 is multi unlocked, not sure it that's common among them all but I'd say it probably is, mine was a standard retailed boxed.

It runs at 3.7ghz fine without touching the voltage (in fact I knocked mine down a touch as I run it passive) and running my ram at 2100 gives a massive boost to graphics performance + ~30%.
 
Well i've sort have settled for these

- Motherboard: Asus F1A75-M PRO AMD A75 (Socket FM1) DDR3 Motherboard
- RAM: Corsair XMS3 8GB (2x4GB) DDR3 PC3-10666C9 1333MHz Dual Channel Kit
- AMD Llano A8-3870K 3.00GHz (Socket FM1) APU Processor

The Asus F1A75-M PRO AMD A75 has a Integrated AMD Radeon™ HD 6000 Series Graphics in Llano APU. How does that compare to the Ati Mobility HD 5870.

They are *meant* to be multilocked.
As highlighted in this document from Gigabyte,

whilst higher multipliers might be able to be set by the board, they're as a rule only meant to be able to clock up to that default via multi.

If you have an unlocked one, bonus. The extra core of the 3870k will still be of use to the OP though :)

As I highlighted earlier, the GPU in the 3870k is a 400 shader part (the GPU is on the CPU, rather than being part of the mobo so the mobo doesn't matter in this case) compared to 720 in the 5750 and 800 in the 5770, and clocked lower (600 vs 725(5750)/800(5770). From experience, having owned one, the 5870m is somewhere between the 5750/5770. Whilst it sounds like a lot of the 3870K's might overclock reasonably well, it's not going to be as fast as the 5870m, that said it should be more than enough to get you going.
Performance wise the 3870k's GPU is going to be more akin to a 5550/5570. If you go Llano and kept my above spec aside from the changing the CPU and mobo to Llano, and dropping the GPU, you should be about £40 better off, and could add a discrete GPU at a later date with a little more cash which, especially with people selling second hand, would be a lot faster. This all being said whilst Llano ISN'T as strong a CPU as the Sandybridge series, the onboard graphics are a lot better than Intels.

Also, unless your needs are way out from what you've stated, you shouldnt really need 8GB of RAM, 4GB should be enough, although the cost differential isn't that high so if thats what you want it won't hurt :)

Not stating a for or against favour but the extra core really won't be of any extra benefit at all. Emulators aren't typically multi threaded. I know PCSX and Dolphin perhaps are but are 2 core max.

Even for normal non emulated gaming its been proved quite a bit that a quad is still only marginally better than even a dual processor.
 
Unfortunately more and more games like BF3 (which the OP mentions) do make use of the quad, not to mention, this is fundamentally a media machine, and multithreaded decoding most certainly uses the 4th core.

The 3870k has a faster built-in GPU, faster stock clock, and another core, it's simply a better chip for the OP to chose if he does go the Llano path here, even more appreciably so if he choses not to overclock for heat/power/noise reasons, simply put it'll last longer.

Deffo now going with the following.

- Motherboard: Asus F1A75-M PRO AMD A75 (Socket FM1) DDR3 Motherboard
- RAM: Not sure yet
- AMD Llano A8-3870K 3.00GHz (Socket FM1) APU Processor

Whats the difference between the Asus F1A75-V PRO AMD A75 & the Asus F1A75-M PRO AMD A75.

I was told today that i need to get the fastest ram the motherboard can take to get the most out of the Integrated AMD Radeon™ HD 6000 Series Graphics in Llano APU. Is this correct? Its mad how fast things change in the components of a pc. With me not building a pc in over 2 years and not kept up with the goings on it all feels so alien.

The main difference I'm seeing the various boards from a quick, cursory look are that the Pro offers 2 more USB3.0 ports compared to the non-Pro. The difference between the *M* Pro and the *V* Pro is that the V is fullsized ATX, whereas the M is an M-ATX (smaller) board.

Also, regards Llano, that's partially correct, however the major jump is between running the RAM at 1333Mhz and 1600Mhz, you get a little more performance going higher, but thats where the main performance jump is involved.

Example
http://www.legitreviews.com/article/1652/6/

As long as you get RAM capable of, and ensure it's running at 1600Mhz or higher, you'll be good to go. The value kit I specced above isn't 1600Mhz only 1333Mhz, so with this in mind I'd recommend a swap to one of the 1600Mhz rated kits. The price difference is minimal. Remember you will probably need to manually configure them or enable an XMP profile in BIOS to get them to run 1600Mhz, as RAM tends to default to 1333Mhz for standards reasoning.

As far as I'm aware AMD chips dont have any issues with 1.65V Ram. The Kingston HyperX 4GB kit should do you well. They're low profile which may be handy if you decide to change cooler at a later date. They're very similar to the GenesisX which is slightly cheaper by £2 right now, but will be going back up Wednesday :)

If you wanted an 8GB Kit, I would personally recommend spending a little extra on the Corsair Arctic White, simply for the reason it's again low profile, but additionally it's specced at 1600Mhz at a very low 1.35V, which means not only will it use a little less power but as it's obviously memory which has binned quite well to be considered stable at 1.35V, at 1.5V it might potentially be able to push either lower timings, or up to 1866Mhz.
