that's about comparable to my old system to some degree. I had great performance with it but I had a GTX480 doing the rendering though and an AMD X4 965 BE as the processor on an Asus Crosshair III Formula MB.
I just built a new system:
- Asus Crosshair V Formula motherboard
- 8GB Mushkin DDR3 2000 (2 X 4GB)
- AMD Phenom II X6 1100T BE OC'd to 4.1GHz on air
- Evo Galaxy 1.2kW PS
- Win7 Ultimate 64bit
- eVGA GTX590
- 2 X OCZ Vertex 3 MAX IOPS 120GB SSDs in RAID 0 (2.02 firmware)
- Zalman CPU cooler
- SoundBlaster X-Fi Titanium Fatality Pro
- Antec 1200 case to hold everything (all stock fans replaced with Arctic Cooling ones)
and it screams

There isn't a game I can't put everything to max on and set AA and AF all the way to max also (@ 2560 X 1600 resolution)
SH5 never looked better
