Well it looks to me like you'd be able to run most things at max settings, probably for quite a while. That would be very powerful machine, better than what I currently have and I can max out almost everything at above 60fps.
Btw, if you have a
Microcenter in your area, they have some amazing deals on processors and motherboard combos right now, but they are in store only. If you go to their site and click on a product there is a store locator on the right hand side.
For example, you can get
This Quadcore 3.4GHZ Ivy Bridge Processor.
And if you buy it with
this motherboard, you get the motherboard for a big discount.
That's a total of only around $75 more than the motherboard and processor you currently have and that processor is way, way better. You are going from a dual core processor to a quadcore and a new Ivy bridge that uses less energy for roughly the price of a new videogame.
However, if you don't have a Microcenter around you, I'd just go with one of the two combos I listed above. Both of those are quadcores too and would be a substantial increase.
