tried it out for a bit. pretty sweet upgrade.
my pc can't handle it as well as i'd like @ 1080p with Ultra settings, tho.
my pc specs:
i5 760 @ 3.8ghz
8gig 1600mhz ram 9-9-9-24
1.5TB western digital caviar black sata2 7200rpm
sound blaster xfi xtreme sound card
2 GTX460 1gig cards in SLI (MSI Hawk Talon Attack cards which are clocked at 850 core/ 1000 memory/ 1700 shader) ...1 card is supposed to be faster than a stock clocked GTX 470 for reference.
Crysis2 was set to 1080p @ Ultra settings/ DX11/ High Motion Blur/ High Textures ... everything maxed ...
using Fraps i was getting 50-60fps a lot of the time, walking around the streets, etc. ...but when combat/action started it would drop to 40-50s. even saw it hit into the 30s one time when a huge explosion went off in my face ...heh.
anyway, not a fan of that kind of framerate, so i dropped it to Extreme settings with High motion blur/ DX11/ High Textures and was getting a solid 60fps.
will keep it that way.
