Question, need answer

Yes it will but I suggest an i5 3570k for the Z77 motherboard

yeah, my thing too is I really just want an i3 2100 or 2120, and i think it will work well, but i think later down the road it wont be a viable solution, even in everyday tasks as surfing the web and simple things. but i dont want to spend 200 dollars. see my problem?

700$ budget....hmmm i see, well get this: http://pcpartpicker.com/p/h6th

i like i like, but i was going to crossfire the 7870 later on, so can you find a suitable PSu, and you can get rid of the HDD, i have a brand new 1TB caviar black, and a 128 GB AData SSD
