I will run it fine, as I was running it all right on a 550gts for a while on medium pretty well. (Though I would suggest taking a look at AMD cards for the cheaper price if you are planning on buying that or thinking of getting a new one if that is the card you have right now. I got a 380 for about 240 a few months back. great card.)
The i3 and will be your biggest problems in regard to speed. Might want to look into upgrading it if you are getting serious. (Also jumping the ram up to 16gb would be a good investment.)
Also, don’t be expecting a AAA fps right away! Start small and learn the engine.
Though this is all just my 2cents!
P.S. What are your current specs? Or is that your current specs right now? (What is the specs on the i3? Cores, GHZ?)
