hi, apart from £10, what would be the difference between :

Specifications
Gigabyte 5770 1GB DDR5 DX11 XFIRE 2DVI/HDMI/DPORT

Chipset: ATI Radeon HD 5770
Core Clock: 850 MHz
Mem Clock: 4800 MHz
Memory: 1GB
Memory Bus: 128 bit
Memory Type: GDDR5
Card dimension: ATX
Bus Type: PCI-E 2.0
Bus Speed: x16
Maximum Digital Resolution: 2560x1600
Maximum VGA Resolution: 2048x1536
D-SUB: Yes
TV-OUT: No
DVI Port: Yes
VIVO: No
Multi View: Yes

and

Gigabyte 5770 1GB DDR5 DX11 SUPER OC HDMI/DPORT

Specifications

Series: Radeon HD 5000 series
Chipset: Radeon HD 5770
Key Features: SOC
Core Clock: 900 MHz
Memory Clock: 4800 MHz
Memory Type: GDDR5
DirectX: 11
D-sub: Yes
DVI: Yes

would i notice a great deal?

I wouldn't have thought an extra 50MHz on the clock would make a huge difference. It's your call if 3 or 4 extra FPS is worth a tenner or not

. If you can run to a little extra, a 768 MB GTX460 would blow both of them away.

I highly doubt you'd notice a fps difference of 50 hz in a card like the 5770, especially if you don't play games like Crysis. However they can both overclock, and I'm pretty sure that they'll both OC to the same level. However I'm not sure that they've been 'binned' differntley, if they are, the more expensive one would be more stable.

Basically, if you're planning on OCing, get the cheaper one.

And even if you arn't, I highly doubt you would notice the difference, but it is only £10.

nearly £50 difference though

paradisiac · 17 Jan 2011 at 10:57

in my price bracket (have to buy from one company through work) are :
HD5770
GTS450
HD6850
GTS240
9800GT

Blue160 · 17 Jan 2011 at 10:57

You can find them for £118 if you look around. How much are the 5770's now?

Edit: ah, just seen your second post. 6850 is by far the best of those

i can get a HD5770 through work for around £79

Blue160 · 17 Jan 2011 at 11:02

That's a great price. Out of the list HD6850 is by far the best option.

the HD6850 would be around the £110 mark, which if its worth the extra then might be better off aiming for that. dont wanna go too mental as i dont really use it a lot, but want to know that if/when i do, im not gunna be hit by lag and poor gameplay.

Blue160 · 17 Jan 2011 at 11:07

What resolution do you game at?

paradisiac · 17 Jan 2011 at 11:10

it will be hooked up to my 1080p tv, so whatever that goes to, think its 19**x*** but cant remember now

paradisiac · 17 Jan 2011 at 11:44

and being ATI i wont need a cable to the mobo for HDMI audio (or do newer Nvidia ones not need it either)? also, will the cpu/mobo (AMD ATHLON II X2 250 AM3, GA-M52LT-D3) cause a bottleneck on that card?

Blue160 · 17 Jan 2011 at 12:43

At 1080p you would definitely see better framerates with the 6850. Rest of the system won't bottleneck it for most things. The 128 bit memory bus on the 5770 is a bit of a problem at high resolutions.

paradisiac · 17 Jan 2011 at 12:47

i had 2xHD5770 on my old i7 system, and found they seemed to cope ok with most things, but wasnt really wowed by the performance.

paradisiac · 17 Jan 2011 at 13:25

is the HD6850 better than the HD5850? what would be the Nvidia equivilant?

Blue160 · 17 Jan 2011 at 13:39

6850 slightly below 5850 although better at DX11 (crackers naming system). Equivalent to 768 MB GTX460.

so would a 1024MB GTX460 be better? do the newer Nvidia cards still suffer from the audio over HDMI issue where you need a cable to connect the card to the mobo?

Blue160 · 17 Jan 2011 at 15:47

No idea about the HDMI issue. My card didn't come with any extra cables so I expect it's been fixed. 1GB is noticably better, but more expensive again. The price for the 6850 sounds excellent by the way.

The HD6850 1GB is actually slightly faster than a GTX460 1GB:

http://www.techpowerup.com/reviews/HIS/Radeon_HD_6850/28.html

It also only requires a single PCI-power connector meaning it also consumes less power too.

An HD6850 1GB overclocked by 165MHZ to 175MHZ for the GPU consumes less power than a GTX460 1GB at stock clockspeeds when under load:

Basically if you can get a HD6850 for £110 you'd be barmy not to
