arrr, damn, i thought u were still to buy the 6600GTs...cuz the x800xl is the much better way to go but okay, now u got the mess,maybe i can help ya out with a good mobo

The DFI-blablub-DLR...wait...DFI LANparty nF4 SLI-DR, thats your new board. But, man why u bought urself these SLI cards....damn, they must be noisy, and furthermore nforce4 has this damn northbridge cooler.Like the DFI. There are other boards too like the Asus SLI and Gigabyte and from MSI. MSI is just too expensive and wont offer any specifical bonus, the gigabyte not only has the northbridge cooler but a unique DPS_Modul, stabilizing whatever with power. And then the Asus...well just have a look into the Asus thread and watch there hassles. Besides some Pentium boards I wouldnt buy Asustek (though my last 2 boards were from Asus) but since some years the quality seems to be rather low in Asus boards. DFI has the most cables and stuff like a frontX-panel compared with the other boards. Comparing these 4 boards would show that the MSI and Asus are slightly faster, then DFI and Gigabyte - but in clock speed. If u look at overclocking features and abilities its the DFI owning the mob. So my advice is:
Buy the DFI
what Memory ya got? Some pretested @PC3700 with UTT, BH5 chips would be nice, Memory has become very cheap but for overclocker memory u still spent at least about 150,- for stuff from Geil, Kingston, MDT, OCZ, Mushkin, GSkill, ADATA.
if u got some mone left...buy a CPU....look for the new Venice Core of course, id suggest a 3500+ or a 3800+. Overclocking these baby will let u play smoothly the next 2 years...the only issue will be ur 66gts....man why???? did u buy them in the days when 6800gts were so hard to get and the X800XL not out yet?

Maybe u need a new HSF too? Thermalright XP-120 + a silent fan with 1000rpm.
