  1. Best answer
    whoever told you to expect 40fps in GTA4 with a phenom processor was very misinformed.

    the game is heavily CPU dependent, and the orignal phenoms were not very good processors.

    a CPU upgrade would certainly ease the bottleneck in your system.
  2. any suggestions of a better gaming cpu for my board?

    maybe this one?
  3. yes that would be a very good upgrade.

    just double check the board manufacturers website that its compatible with am3 chips (it should be, most are).

    if it is, it would be a very good upgrade.
  4. is there anything i can do in the mean time?

    i was going to upgrade to this with income tax ...

    im new to the gaming side of computer building so sorry if i ask stupid questions, but i assume these componants would help?
  5. yes they would, the phenom II 965 is a great processor, and having a newer MOBO would help with OCing and general performance.
  6. thanks for the help hopefully that will get rid of this lag i can not even do missions :fou:

    unfortunately, GTA4 is a poorly coded game that doesn't run well on low-end gear. GL though.
