I just finished my 1st build and used SiSoft Sandra Pro06 for the burn in. Then used 3DMark06 to get a benchmark. Here's my system,
Intel 3.2 Dual Core I swiped from my Dell
Zalman 9500 CPU Cooler
2- EVGA 6800 GS
3 gigs DDR2 Ram
Case- Thermaltake Kandalf
Without Overclocking I got a 3Dmark score of 4439
Seems a little low to me but I havent turned up the heat yet. I need to do a little studying before I get into this.
Look at my sig for my pc specs... and there's also a link to my current score with an OCed AMD 4200+ and X1900XT... so in comparison... i reckon you have the right score for your rig, IF it has been tested on 3DMark2006....
Unload both of those for $169 each or so, and get a single 7900GT, pocket the remaining $38 for use at a strip bar or restaraunt, and watch your gaming performance double easily, and at two steps higher resolution to boot...
