Jarmel :
I have my i7 870 OC to 4.0 ghz yet when I run 3d MarkVantage I get 10,000 under CPU score for the performance settings and weirdly enough 11,000 under the high settings.
My old SLI rig:
MB: MSI K9N Diamond (AM2) PCI-E x16/x16
CPU: AMD Athlon64 X2 DualCore 6000+ 3.0Ghz CPU
RAM: Corsair Dominator TWIN2X DDR2 1066Mhz 4GB (2x2GB) CL5 (@ 800Mhz + CL4 timings)
GFX: 2x XFX Geforce 8800GTS 512MB 650M
OS: Windows 7 Ultimate 64 Bit
3DMark Vantage Score (Performance): P12350ish
My new SLI rig:
MB: Gigabyte GA-P55A-UD4 (1156) PCI-E x8/x8
CPU: Intel Core i7-860 2.8 Ghz
RAM: Corsair XMS3 DDR3 1600MHz 4GB (2x2GB) CL9
GFX: 2x XFX Geforce 8800GTS 512MB 650M
OS: Windows 7 Ultimate 64 Bit
3DMark Vantage Score (Performance): P13457 (GPU: 11044 - CPU: 39051)
Both system scores are with stock clock rates. Gotta say I'm happy with my i7-860 there. I can't fathom how your i7-870 performs that bad.
