The Specs of this computer...

[Lyra]

I'm thinking of buying the following PC:

Specification

Intel Core i7 950 Processor - 3.06GHz NOW 4GHz+
Corsair H50 Water Cooling
6GB Corsair XMS 3 Memory
Asus P6X58D-E Motherboard
Corsair 600CX Power Supply
Seagate 500GB SATAII Ultra Fast Hard Disk
Gainward Geforce GTS 450 "Goes Like Hell" 1024MB Overclocked Performance Graphics
Ultra Fast Samsung DVDRW
7.1 High Definition Surround Sound
10/100/1000 Ethernet LAN
2x USB 3.0 Ports
8x USB 2.0 Ports

As the idiot I am, I have little to no experience with gaming on a computer. I really would like to know if this computer is powerful enough to run oblivion on high with a playable framerate. Can anyone with experience help?
