i use vista ultimate 64bit

my system specs are:

2x 1TB HDD's raid 0

6GB OCZ Sli 1.8Ghz DDR3

2x Evga GTX280 Superclocked 896 mb in sli

I use, personally, Vista Home Premium on a computer originally with a Centrino Duo processor, 1 GB of RAM, 120 GB HD. I upgraded the RAM to 2 GB and had to replace the hard drive and optical drives. If I had the choice, knowing now how poorly Vista runs on less specs than XP, I would've kept XP. But now that I upgraded the mem. it seems to run much smoother.

BTW: I have a integrated graphics chip.
