Thats the case if needed, not the same insides but same case.


My budget is about £150/$244, i aint too bothered about it looking amazing, just descent and smooth.


I just play classic games mainly when i feel the urge to play the likes of Black & White, AOE 3, most strategies.


But i do want to play other games its just they lagg too much so i presume my system cant handle it, hence the upgrade.


If you could recommend a decent PSU+Graphics Card that would be great.

I was thinking
BeQuiet Pure Power L7 530W '80 Plus' Power Supply [BN106]

For the PSU would this work? stupid question do all PSU's come with the same cables to power devices, or would i have to pick a PSU with the right cables to power things?

And i was thinking
Sapphire ATI Radeon HD 5850 Extreme 1024MB GDDR5 PCI-Express Graphics Card **OcUK Exclusive** [11162-15-20G]

For the GPU, but ideally i want a GPU with VGA, i havnt got the funds to buy a new monitor and that runs off VGA.

I looked on my motherboard and removed my GPU but it didnt say anything like PCI-E or PCIe x16, im not sure whether it has PCIe x16, and there isnt allot of information coming from google regarding my mobo.

Is there any software that will tell me the connections my mobo has, so i can be certain it has PCIe x16.

Think this is my mobo, atleast it looks like it without the 2 devices plugged into the PCI slots.

Going on the picture above do you think EVGA GeForce GTS 450 1024MB GDDR5 PCIe will fit in there?

LoL i got the picture from google its not my actual system, that fan though does get clogged quick i have cleaned it before and within a month its full of dust, the 2 PCI slots on mine are both empty so i should be good with any dual slot card.

Thanks for recommending the card, but its a little expensive and comes with games which probably make it more expensive, its also quite large i dont know whether it would fit.

Im starting to lean towards the EVGA GeForce GTS 450 1024MB GDDR5 PCIe, i have been recommended this card by about 4 people. Do you guys think this card is any good?

Hmmm might go for the 5770, but im not sure about the single slot it isnt really needed, did you install the single slot version rolypolyman? if so whats it like ie running temp.

Does the one linked come with a DVI to VGA? As my monitor is VGA.

Taken from another forum:

low speed dual core will probably bottleneck the video cards max performance a bit, but will still be light years ahead of what you have now, so you won't notice it.

If you do upgrade your CPU to a faster 3GHz range Dual or Quad core, or even an entirely new PC/Platform (whether its newer AMD or Intel CPU's) you should notice a decent boost in performance, once the cards max potential is unleashed.

Even though your card will be bottlenecked if you got one of these 2 listed, and in effect you'd be paying a bit extra for limited performance (keep in mind though, that the limited performance is so many times over what your current card is capable of, its hard to quantify), in a way, its future proofing yourself to some extent in the fact that if you did get a better CPU or PC down the road, you should/would have the same video card, but with extra unlocked performance, until you could get something better.,

i will probably upgrade the CPU at some point, what CPU would you recommended for about £100 cheaper if possible to go with the HD 5770?

Altogether my budget is £330/$538 dead, that seems like a decent amount for what i need surley there is a bundle with all this together or something.
If not can you please provide links, to where i can just buy the stuff and get on with it.

I dont really want to mess around with the mobo, is a new mobo important? and what are the advantages of a new mobo?

Is there no bundles or anything where i can get all this in 1 go on the cheap? Because paying for it all individually is costing allot.

Thank you all for your time researching this stuff, im learning allot aswell.
