what game can i play???i mean on medium and low spec...
and is my processor bottlenecking my GPU performance??
if so, what upgrade should i do??(i just brought this gpu....i just wan to upgrade my CPU)
If your motherboard says it can upgrade to a core 2 quad i would do that.
I would say it's mostly your CPU thats hurting you FPS wise.I have a card similar to yours the Radeon 5570 and i play L4D2 maxd out 60+FPS.As for CoD Black ops i can max out everything and run that too.I have problems with BFBC2 just like you but thats a GPU problem for me.I have a Phenom x4 965.With an upgrade to a quad core you should see way betteer results in FPS but if you want to play some more demanding games then you will ahve to think about getting a new GPU.
I'm reccomended that you get a new CPU,the Core 2 Quad.
only the newest games "reccomened" having a quad core.In a few years it will be "minimum" to have a quad core.So yeah it should last a couple years.I would think about upgrading your GPU sometime in the future though,with a quad core the GPU should be the only thing you have to upgrade to keep up-to-date on upcoming games.
