Hi there. I recently switched my sapphire 4870 with a new 5970. The main reason for this was I kept getting BSOD's which couldn't have been more convenient, because I wanted the new generation card anyhow. The problem is, I'm not seeing any performance gains at all when I play games. Using WoW as a benchmark, I'm seeing 60 fps with my 5970, and 40 fps under more demanding situations. Those were the same exact numbers that I was getting with my 4870. I just learned what bottlenecking means (still a newb to the pc building world) and I was wondering if anybody could tell me if that's my problem, and if at all possible, how to fix it.
Here's my PC in a nutshell:
Asus m4a79t Deluxe Mobo
AMD phenom II x4 955 BE
4GB corsair xms3 1333
ATI Radeon hd5970
Nothing is OC'd. Any help would be appreciated, thx!
WoW isnt really a game that will benefit from dual GPUs and its not a benchmark at all. Try running Crysis or some more intesive game. And try ocing your cpu , that should help a bit . If you still have the 4870 put it back and bench with 3dmark and then bench again with the 5970,mine is on its way, btw whats your powersupply brand and wattage?
ahh okay, sounds good. i've actually been reading articles and articles on how to OC, but i don't think i'm ready just yet. but i'll definitely take that advice.
the PSU i'm using is a corsair 850w.
Can't find your answer ? Ask !
I have the same PSU so no problem there. Hers an interesting read about the HD 5970 and Cpu scaling with phenom http://www.legionhardware.com/document.php?id=869&p=12 , ATI seems to run better on weaker systems so it doesnt really need a 4Ghz processor as most people think, the phenom 955 @ 3.2Ghz is more than enought as you can conclude.
