Any motherboard, no matter how old, with a PCI-E slot can handle ANY of the latest graphics cards.
The main areas of concern with a GPU upgrade are:
- power supply, is it enough to power the new card. A good 650watt supply will power any SINGLE card. Even if your 750watt is not a top brand it should be okay. Please LIST the brand and model of supply you have so we can double check....
- CPU speed. If you have a really old CPU like a single core, you CAN use the new video card, you just might not see all the performance that would be possible with a newer CPU.
Please list the CPU you currently have installed so we can check if it will hold your system back at all. (the good news is since you have an AM2+ you could upgrade the CPU alone IF Need be.. for optimal performance)
If after you install your new video card that your not getting close to the FPS that reviews publish for the card or, that meet your gaming needs you can update your CPU to just about any of the new AMD chips.....
NOTE: if your getting 40 FPS and a review of your card says you should get 70 FPS for a given game, I'd look to a CPU upgrade.
- if your getting 40 FPS & the reviews say you should get 45 FPS, I would Not upgrade the CPU as it's unlikely you'll gain much if anything.
Just locate the latest BIOS for your motherboard (on Gigabyte site)
Download and re-flash the BIOS using there supplied program
NOTE: this MUST be done with the OLD CPU installed.... (without the update the new CPU won't work...)
Then pop in something like an Athon II quad core for $99....
