I'm planning on building a general use build for my younger siblings (four of them, youngest is 5) and I'm budgeting at around $600 for the hardware and case (plus eventually perhaps a screen and mouse/keyboard, but that's not part of the main budget, since we have spares of those lying around). Not looking for any big bells and whistles, just a decent build capable of handling browsing, schoolwork, and movies (perhaps gaming, but we'll get to that in a second.) I like putting machines together, but any combo deals or cost effective prebuilt deals would be OK.
If possible I'd like to build it on a micro ATX form factor, but price/performance is more important to me than form factor.
About gaming: I have a spare GTX 560ti that I recently pulled out of my mid/high end gaming build (Dual 660ti FTW edition now) and I'm considering dropping this into the new system. Without straying too far from my $600 budget (maybe go up to $800, if absolutely necessary) what would I need to make sure this graphics card isn't handicapped by the rest of the hardware?
