IMO - Yes a CPU is important for gaming, but i believe that the videocard or cards you use a just a hint more important.
I believe that upgrading a CPU should be directly related to your videocard solution.
If you're going FX-57, then an SLI or CROSSFIRE solution is probably the best way to go. You'll need a very high-end CPU to keep up with the Highest settings in AA & AF and monitor resolutions. You'll also need the highest-end videocards available.
If you're in going with a low to mid-end videocard and you'll already be limited to mid AA&AF settings and resolutions, so a mid-end CPU is probably the best upgrade.
Any of those CPU's that you listed would be a fine choice for a mid-end videocard. Using a Highend video card like the 7800GTX or the X1800XT would be fine with any of those CPU's but, don't expect to use the highest settings or resolutions for monitors over 19". It will work just fine, but the performance won't exactly be top notch.
STRICTLY IMO,
Your CPU & VIDEO CARD for "GAMING" should relatively be matched for their best performance.
Are u saying with the 4400 X2 I should'nt expect the highest settings? Even with 7800gts in SLI?
