GPU, decisions decisions!

so, i have been able to up my budget a little and have found thease cards, I think i want the MSI it seems to have excellent cooling system as far as i can tell and is more powerfull. But is what are your opinons on the matter? This is as high as im able to spend. Anyway here are the links and prices, i need to try to decide tonight if i can

Totally pwns the 8600's.

The MSI is overclocked 25Mhz core and 100Mhz memory and has a one year warrenty.

The eVGA has a lifetime warrenty and they have an upgrade trade in program.

I would buy the eVGA for warrenty and you can overclock it on your own.

Does the DX9 ATI work with Vista? I was under the impression I HAD to have a DX10 card, but if its so much more powerfull and does work then it looks yummy...

Should work with DX10 games in DX9 with good frames for a good while right? better then an 8600 even?
