I have a 380 Watt coolermaster PSU and just bought a sapphire 2600XT. Bioshock works great, but in world of warcraft a few things happen:
When I enable anti aliasing the max fps drops to 21 regardless of whether I use 2*, 4* or 8* AA.
Performance in general seems much too low sometimes, not all the time for the 1024*768 resolution I play in.
Also when I try to overclock the card with ati overdrive, I get blackscreens @ 810 mhz (normal is 800) even tho gpu temp is still very low (around 40).
Blackscreens after which atitool resets my card and I go back to windows.
2 12 volt amps on the cooler master PSU, one 10 amp and one 12 amp.
I have one HD one DVD player.
that would seem weird, (unless its a glitch whereby it just applies the same amount of aa regardless of what you set it to which would be odd) but I wouldn't imagine it would be a PSU issues unless you get artifacts or random restarts
Hmmm yes that could be an option of course.
I did hear somewhere that performance issues can also be result of a PSU problem, but I would really like to be sure about this before I spend 100 euro on a good PSU.
