hi guys im planning on upgrading my gpu
I have a core2duo e7400(2.93ghz)
and 4 gb of ram
thx in advance guys...
a 650ti or 7750/7790 might be an option. Really though your wasting money. The old C2D was a good chip in it's day, and although it still good for most things, isn't going to be a future proof gaming rig or anything remotely similar. The cards above, would be a balanced match with your system. Just don't expect stellar performance with that system.
The cost of the cards is prob around 100-150. If I were you I would save that money, add another couple of hundred, and look at a new entry level gaming system, which will serve you much better.
