Iv actually been bidding on that one already. LOL Yeah a mild OC, nothing extreme. Are there any ATI or nvidia chipsets that would OC? Or mainly P43/945?
The nvidia 790i chipset boards are typically good overclockers (from my experience), but they also cost a small fortune. Typically $150+ is not unusual from what I've seen, some go for over $200. These can be found in EVGA, XFX, and ASUS branding (don't think any other companies made them, but I may be wrong).
The 780i chipset boards are also quite good, but while cheaper than 790i boards they still aren't exactly "cheap". You're looking at $70-120 for a working one usually. These can be found in EVGA, XFX, and ASUS branding (don't think any other companies made them, but I may be wrong).
A 750i would probably give reasonable performance, and they're usually cheaper than their newer brethren, but perhaps not as good at overclocking. These can be found in EVGA, XFX, and ASUS branding (don't think any other companies made them, but I may be wrong).
Other good boards: EP45-UD3P (revision 1.0 and 1.1 are best, revision 1.6 not so much) (typically $60-120 last I checked), EP45-UD3R, Asus Rampage Extreme (typically $100+), Asus Maximus Formula (X38), Asus Maximus II Formula (P45), DFI Lanparty P45-T2RS (P45 DDR2 memory) DFI Lanparty P45-T3RS (P45 DDR3 memory). There may be other good boards out there, but these are the main ones I can think of off the top of my head.
The DFI one's are nearly impossible to find, but I've heard they were good boards.
