O'C CPU and get RAM or Crossfire 4850?

I want to increase general performance. Someone on Kijiji is selling an ASUS 4850 for $40. Should I buy that and run crossfire?
Should I upgrade CPU to another AM3? Should I O'C and get another 8gb of ram?

This build is really old now. Need some help. Thanks!

Approximate Purchase Date: Within 2 Weeks

Budget Range: Under $300

System Usage from Most to Least Important: Watching HD video, video conversion and a little gaming (Starcraft 2, etc.)

Are you buying a monitor: No

Parts to Upgrade: CPU, GPU, or RAM?
Do you need to buy OS: No

Preferred Website(s) for Parts: NCIX, Canada Computers

Location: Toronto, ON

Parts Preferences: n/a

Overclocking: Maybe- I'm open to it. Like if I should o'c instead of upgrade CPU and spend money on GPU

SLI or Crossfire: Maybe Crossfire

Your Monitor Resolution: 1920 x 1080. If possible 3D

And Most Importantly, Why Am I Upgrading: No real reason. That's sort of why I wanted some advice. Not that I have money to burn, but I enjoy upgrading. However, I would like to be able to use three displays at one point. (all through HDMI)

Current System:

Mobo: Gigabyte- GA-MA790FXT-UD5P
CPU: AMD Phenom II 710
RAM: 4GB DDR3 10666
GPU: Saphire Radeon 4850

  1. Oh, and PS is OCZ Fatal1ty OCZ OCZ550FTY
  2. if your playing SC2 which is a bit of a CPU hog, I'd suggest you get a Phenom II X4 965 (happens to be the best I see on and maybe get another 4850 or finally upgrade to either a 7xxx or 6xxx. I say maybe because you may also need to upgrade your PSU - not sure
  3. Best answer
    honestly, probably the 965 the mc suggested and an AMD 7770. ram is still OK. then there is no PSU question and you have an efficient GPU with DX11
  4. ^ +1 wiser words have never been spoken - looking at a quick $250 upgrade that'll bring your system into this century =p
  5. Thanks for the advice!

    Is there any reason in particular you would suggest a x4 as opposed to an x6?

    Should I just overclock and spend more on a GPU?

  6. ^Thuban's don't generally add much performance to games when compared to denab.

    Have you tried unlocking that dormant core on your 710? If you can, then overclock it to have similar performance of a 965 (If it is even possible.) If you do this successfully you could invest in a 7850.

    If you are unsuccessful then my advice would be to go the 965/7770 route.
  7. @zooted. Thanks very much for the input.

    I'm going to try to unlock the fourth core today and overclock. Then 7850 time.

    If my 4th core is defective 965/7770 sounds like a good plan!
