Cool.........guess I didn't check the ati graphics processor wiki before I posted that.
I'm sure it will be fine for AHII since it runs sweet on a asus 4a785-m (integrated ati hd4200)with phenom II black edition 555. (unlocked the other 2 cores but running now on 2 because I haven't needed them as of yet).
The only "game" I have run into that really benefits from more than 2 cores is FSX and it seems FSX is more about the general processor itself than the GPU (assuming GPU is of any decent performance).
FSX could really care less if you have more than 2 cores, and that's an improvement compared to before the first Service Pack (had basically no multi-core support before the service pack). When I'm playing FSX the game is only using 1.5 out of 4 cores (doesn't seem to utilize the second core fully).
Where FSX sees the most performance gains is in memory bandwidth, which is why the i7's are some of the fastest FSX rigs out there, their memory bandwidth is absolutely absurd. The GPU is basically useless in FSX, my 5770 doesn't register hardly any utilization when playing FSX...

In fact, one cool thing I've found about this is that you can turn AA and AF on in your graphics card and leave it off in FSX and see no performance loss. However, if you turn AA on in the FSX settings, the CPU sees the added load.
