To get this out of the way: specs Abit Fatality FP-IN9 Intel Core 2 quad Q6600 (4x 2.4GHz) stock cooling 2x XFX Nvidia 8500gt Graphics Cards (x8 x8) 2x Patriot 1024MB ddr2-800 running at 5-5-5-15 Samsung 500gb harddrive (sata) no overclocking Now then, a while back, I bought Overlord. I've noticed two things: One, good game, and two, I lag horribly at the highest settings. Basically, how do I find any bottlenecks which might impede performance, and if there are any obvious problems with my setup, how can they be solved (cheaply)? And another thing, while on the hunt for a better Mobo, I ran across a few articles stating that there is no obvious performance boost between full x16 sli and x8 sli. It has also been a long, arduous trudge to find a mobo under $200 that offers double x16 sli. Is it worth it?
