Replacement card

[pkw4]

Hi, i have just ordered a HIS HD 2900XT 512mb gddr3 to replace my dying xfx 8800gs 384mb (flickering screen in games farcry2, crysis and anything gpu heavy). Will this card be any better? i getting it dirt cheap brand new and would like to know how this card wiould preform in modern games.?
was this a good cheap choice (£25), my psu is up to it.

Yeah, it should be a slight upgrade although nothing huge.
Uninstall the Nvidia drivers and run driver sweeper in safe mode before installing the ATI drivers for the card.

What will be different is the power use/temps. The 8800GS used very little power and ran cool. The 2900XT was a hot hungry card. You said it was, but make sure your PSU is up to it. No, just because its 600W doesn't mean that it is.

my psu is 500w with 36amp in total over 12v dual rails, this surley could power it. another question is would this card run with 2 6pin adaptors? i read it can use 2 6pins or 1 6pin and an 8pin but i have 2 6pin adaptors.

It should run with two 6pins. The 8pin is needed if you want to use CCC to overclock it.

Also, just because each single rail is rated at 18A doesn't mean the source feeding them can power both at the same time at full power. For example, my PSU rates each single rail at 22A, but can only do 34A combined, not 44A. Look for a total wattage number for the 12V rails to make sure it can do 36A.

If your budget permits, pick up a HD4770, HD4850, or HD5750. Any of those would run on your PSU, and would be considerably faster than the HD2900XT.
