My system is as follows:
Intel(R) Core(TM) 2 Quad processor Q8300 [2.5GHz, 4MB L2, 1333MHz FSB]
4GB DDR2 Ram
1GB NVIDIA GeForce GT 220
250w PSU (stock)
I'll be upgrading my ram to 8GB DDR2 as well as my graphics card to a EVGA GTX 550 Ti Fermi 1GB 192-bit. I'm wondering if anyone can tell me how big of an improvement I'll see (mostly FPS-wise) in current games such as Star Wars: The Old Republic, Diablo 3, etc.
Obviously I'll be upgrading my PSU as well to a 500w Rosewell ATX12V.
Will this upgrade be bottlenecked by my system or will I see a huge performance improvement in most games?
