I recently ordered almost everything for my new build from scan. It's not been great. I sent the first of my graphics cards (Nvidia GTX 275 XFX XXX edition overclock) back , and got a replacement for the faulty one.
Now the new GTX275 (same model) seems to be overheating. If I'm running something intensive (i.e. COD MW2 high specs) my system hangs and the graphics card reads around 83C just before.
I7 920 CPU, stock cooler
Gigabyte GA-EX58-UD5 Mobo
Corsair TX750 750W PSU
XFX GeForce 275 GTX XXX Core Edition GPU
6GB Corsair Dominator RAM CAS 7-7-7-24
Thermaltake Element G fan
1TB Samsung HDD
Please help, is it my motherboard killing my GPU?
Any more info needed, please say
