Hello there I figured out a few days back my games isn't performing as they should be performing, and I wanted to no is it my CPU that is bottlenecking or is PSU not giving enough power to my system. I think its both, I tested this with Need For Speed: Most Wanted 2, L.A Noire, Prototype 2 and my Skyrim is a bit laggy so my specs are: CPU: Intel Celeron D 336 2.8GHz over clocked to 3.6GHz GPU: Asus Radeon HD 7770 PSU: 350W I now my GPU needs at least 550W to run at full load (The Radeon website says it needs 550W to run at full load) so please give me your info on this topic. Thanks in advance :thumbsup:
