Hey Just got a HIS IceQ X 6950 got 4gig of DDR3 and Im running games like skyrim and crisis ultra 1080 res, but fps must be under 30's its a bit under the point where a game looks 'smooth'. I want it smooth! Ive currently got a Phenom II X2 545 3 Ghz and im thinking its the snag, looking to get a quad but dont want to buy something that wont change anything. any reccomendations? got £100-200 to spend and it will have to be a phenom. Ta!
Most games do not use more than 2 cores, the are some that can use 3 cores, and very few that can use 4 cores. Skyrim and Crysis are examples of games that only use two cores.
A quad core can marginally improve performance of games that only use two cores because background processes can run on the two other cores. But background processes generally do not use much processing power. To ensure games run faster, then you must buy a processor that is clocked faster than your current CPU. Therefore, you need to look for a Phenom II X4 that is faster than 3.0GHz.
Also, after a certain point as long as the CPU is fast enough, you may not see much of an improvement in performance (if any) as long as the CPU is not bottlenecking the graphics card.
