Save your money on the 6700 and go with the Q6600(...running stable here at an easy 3.2) And you could splurge on the 790i and future proof some.....

Go with the EVGA 750i. You said you don't need tri-sli, you don't plan on using more than one hard drive. THe 750i overclocks well, still offers RAID 0, 1, 0+1 and SLI for the future. Very good board, save some money and go 750i FTW!

If you wanna get technical about it the 780i does offer better performance, but its not worth spending the extra $50 on if you are on a budget.

could you be specific about what performance is better im under the same cercumstances as OP'er and would like to know exact performance difference.

There are only two differences as far as performance. First is the number of PCIE lanes. The 750i only supports 1 x16, 1 x8, and 2 x1 simultaeous connctions. The 780i can handle 3 x16 + multiple others (total of 62 lanes) at once. This gives more performance for SLI, plus gives him the option of SLI + raid controller in the future. However, unless the OP is running an extremely high resolution, the performance difference isn't going to make or break his gameplay.

The second difference is the memory controller. The 780i can, on average, overclock memory to a higher stable bandwidth than the 750i. However, this difference will only come into play when reaching for the absolute highest speeds (1200MHz+), so unless the OP plans on buying some expensive DDR2 it won't matter. And if he wants to spend that kind of money on ram, he might as well just go for a 790i+DDR3.

Well I guess there is a third, which is that the dual gigabit cards on the 780i support load balancing which means that he can team them up for a 2Gb/s connection. But that is really useless in 99% of homes.

And the 780i will be able to OC a Q6700 to 3GHz, that is certain. The only catch is you might end up hitting an FSB hole on the way, which makes it more difficult. The solution is to run at an extra high FSB, past the hole, and just drop the multiplier to get the speed that is stable.

You are wrong , get your facts strait, we are not discussing a regular 750i, we are discussing a evga 750 i FTW, which is totally different, its not a reference board, it has full 16 x 16 in sli with 2.0 support.You "might" have some ground to stand on about the memory controller but I'm running 1066 ram at 1100 and have had no issues, and i would bet that it would handle 1200 ddr2 just fine.\\

nope your wrong about the memoy to , i just checked corsair and the 750iftw supports TWIN2X2048-10000C5DF 1250mhz ddr2

they both have the same nb so same mem controller, it is possible the 80 gets the cream from the top bins and the 50 gets those that just pass but nonthe less they are the same. its the sb where the main differences are.

if 50 will fill your needs then the extra money spent on the 80 is just wasted in truth as you wont be using it.

i thought the 750 ftw was a ref design just with uprated caps, regs and cooling?
