Will the Q9550 2.83ghz with 12mb cache bottle neck a gtx570?

Im thinking about buying a new graphics card.... the gtx570. My question is, will the gtx570 out perform my sli'd gtx275s to the point that it is worth 375$? and, will my Q9550 (2.83ghz, with a 12mb cache) bottle neck the gtx570 to much|||Probably a little bit, unless you overclock your Q9550 some. I've had a 570 GTX for a few days now + Core i7 870 @ 3.5 ghz and it's an awesome card. It's a graphics monster and runs surprisingly quiet and cool. You can get one for $335-340 if you shop around|||Im pretty sure it will even in raw performance. It has 3D vision, full CUDA and all the other new specs from the Fermi Range.

It takes wayy less power and leaves room for upgradeability.

The Q9550 shouldnt bottleneck a single 570 though i suggest a six core 1090T or 980X if your going to do SLI|||Stay away from Nvidia. All it is, is HYPE! You want the new ATi 6870x2. Compare the specs in every way to any top of the line Nvidia card.
