Hello. I was considering upgrading my Q8400 and motherboard to get an i5-2500k for gaming. I play a ton of games, everything from World of warcraft, diablo 3, GTA, battlefield 3, etc. I run most games on full and can't seem to do that with with battlefield 3. I tend to play BF3 on Mid/high settings and I get great FPS but every once and a while it stutters and I am hoping upgrading my processor would greatly improve my gaming preformance.
My question for you guys today is, Will I notice a considerable difference in gameplay / FPS if I upgrade my card to the i5? I don't want to spend 300 dollars (including motherboard upgrade) and get something that will help me out okay. I am looking for a game changer so to speak.
I am also worried that my 4gb of ram at 1333 will bottleneck some game considering my processor and video card.
Going form the Intel® Core™ 2 Quad to a 1st generation Intel Core processor would yeild a performance improvement of around 15% to 20%. Going from 1st generation Intel Core processor to a 2nd generation Intel Core processor would yeild around 10% to 15% improvement. This is all at the same speed of all the processors in question. The about 500MHz speed difference at base clock speed and a great deal more with Turbo Boost. Now if you are doing something like gaming you may not see this big of an impact but you will still some a big improvement.
I had an old Q8400 @ 3.2ghz with GTS250. Upgraded to 2500k with a GTX570 last year and whoah performance boost is way off chart.... Just kidding. But definitely it was a great upgrade. Of course considering today there are Ivy bridge out there that are more powerful that you might want to consider.
