I know DX11 is out, but I'm not a hardcore gamer and I probably won't play vvery many dx11 games for a while. My two biggest questions are: will this set-up work (nothing being bottlenecked) and will it be upgradeable in the future (does it have a future?)

You want a new motherboard and DDR3 RAM with a new CPU. Why not the Gigabyte MA770T-UD3P for a motherboard?

Is your old hard drive SATA 3GB? If not a new high speed 500GB single platter HDD like the Samsung F3 or Seagate 7200.12 is $50-$55 and would be strongly recommended.


Upgradeability:
*With a new AM3 motherboard the new 6core AMD CPUs (bulldozer) are supposed to fit in it.

*You have one graphics card slot that can handle a much more powerful graphics card if you decide to swap out the 9800.

* Can get up to 16GB DDR3-1600 RAM if you ever need it. (For now 4GB should be plenty).

* Up to 6 SATA devices (Hard drive, Burners, Blue Ray). 8-12 USB 2.0 ports.

If thats not enough you need a bigger budget.

Thanks for the quick reply! The MA770 looks like a better choice mainly because its cheaper. I haven't even heard of the 6 core AMD CPU's but it feels good to know I can probably upgrade to one when the time is right. The HDD might be in the near future, because the old one is almost full anyways. Thanks again, canadiano
