Fast answer wanted please, which will perform better?

[harris1986]

which will perform better out of a 6800gs pci-e 256mb or the 6800 ultra's with 256mb and pci-e? i'm just thinking of going sli with one of these.

The 6800 Ultra

 

[harris1986]

so the 6800 ultra's will out perform say a XFX GeForce 6800 GS Extreme XXX Edition 256MB GDDR3 TV-Out/DVI (PCI-Express) - Retail (GX-056-XF) ?

 

[benjo]

Yeh it would, unless you overclocked the 6800GS to the ultra speeds (afaik)

 

[harris1986]

kool, i hear the 6800 ultra's eat power supplies for breakfast, will a 400w supply be sufficient?

 

[chaparral]

A single 7800gtx is about the same speed as a pair of 6800 cards in sli..

Not for 2 in SLI I wouldn't have thought, and as said a 7800GTX would make more sense than 2 6800Ultras.

6800GS (OCuk) is £140, if you were able to get the ultra they would probably be £200+ new. As said get a 7800GTX, even a 7800GT when clocked wouldnt be far off SLi and also wouldnt require a new PSU

 

[harris1986]

hmm interesting, the thing is i can pick a brand new 6800 ultra up for £150 pci-e, now would this be a better value for money than spending a extra £150 on a 7800 gtx? also will a 400w psu run 1 6800 ultra ok?

 

[FrankJH]

atmittedly its a bit more than your price for a 6800 Ultra, but I would spend £60 or so more and go for 7800GT, rather than spend £300+ and go for gtx

I would also shy away from going prvious gen at this stage, it seems sily to me to invest a reasonable amount of money on old tech

A decent quality 400w psu will run any single card ( maybe barring the 512mb cards) however if you let us know what kind of psu you have, I am sure some kind person will let you know if its capable of doing any new card justice

 

[Arcane]

It depends on what 400w PSU you're using, if it's a quality one then it will run a 6800ultra ok, Nvidia states a minimum 400w to run it iirc.

The Leadtek 7800GT is £189 at the moment INCLUSIVE of VAT from OCUK


Well worth the extra over the 6800 Ultra
