I want the best thing I can get for this computer, not something too overkill that the cpu or the AGP 4X bus will bottleneck.
I have this on mind. Planning to buy in a a month.
But there are some problems. In the newegg page it says it supports AGP4X/8X, but in Biostar's site it says AGP 8X. Also, it doesn't say anything about the power supply, I currently have a 400W (well, it says Output: 400W).
The 6800xt is a 8x card, which is backwards compatible to 4x operation. And there will be very little difference in performance when using a 6800xt with a 4x AGP port !
But maybe more important is that to get the best from your new card, you should also consider overclocking the VGA card and your cpu/mobo ?
And unless your 400W PSU is a cheap generic type, it will probably be ok with a 6800xt ?
For a 68xxxx series card it's generally recommended that the PSU have a +12v rating of around 15-20 Amps ---> and I mean real RMS amps. The PSU is the heart of the computer, so always important to go for best quality version you can afford ?
With PSU's, the basic rule of "if you pay little, you get little for it", really is true !!
