Is my CPU bottlenecking me?

Intel Core i3-2100 Dual Core @3.1 Ghz // Antec 550 watt PSU // Dual Radeon 7750 GDDR3 2GB on CF // 2x Patriot 4GB 1333mhz RAM @ 9-9-9-24 // Intel DH67BL MOBO

It's used strictly for gaming at non-HD resolutions like 1366 x 768 x 32 on medium - high settings. Should I spring for a Quad core i5 or is the i3 adequate? Emphasis on adequate.

  1. An i3 2100 will not bottleneck with a 7750. 7750 is on the low end for graphics cards that are gaming capable. A better GPU will help you more than a new CPU.

    Is it still true even though I have dual 7750's running on Crossfire?
  3. Yeah to even ask the questions you would have to be looking at a 7950/660ti or some sort lower end xfire/sli.

    Lower end would be like 7850x2 or 660 gtx sli, I believe a 7750x2 performs like a single 7850 at best (would also depend if GDDR5 or 3) which your CPU would not be an issue.
  4. You may run into issues in online shooters like BF3, simply because they react better to quad cores. Probably not enough to be a big deal, however.
  5. At those resolutions you are not being bottlenecked at all by your CPU.
  6. Low resolution games become CPU bound so I will go against the flow and say you are not getting full use out of your GPU's.
  7. no current i3, i5, or i7 can be bottlenecked. Getting a bigger CPU won't hurt but you'd see a bigger performance jump with a better GPU than with a CPU.
