I'm building a PC for a friend, who mainly wants it to rip and edit Blu Rays into "clips" where he adds his own music and title cards and such, along with some very light gaming. He's working on a pretty firm $750 budget. We already ordered a processor and motherboard (i5-3570 processor, figured that was the best bang/buck for a weekend hobbyist), which came with 8GB of free RAM with the combo. That pairing came to $321, so he has around $430 left for the rest of the system. He doesn't need an OS or mouse/keyboard/monitor, but still needs a Blu Ray burner, case and power supply, hard drive, and a video card.
Now, I haven't really kept up with video cards since I built my rig in 2010. So I'm wondering whether he should get a 660GTX or a 650GTX ti for the video card. The most current games he wants are the L4D games, and I can pretty much guarantee he's the type who will never own more than a dozen PC games over the lifespan of this system. There's around a $50-75 difference between the two models. So I'm asking if the bump in performance will be worth the extra $75 considering what he'll mainly be using it for, and that he's only got $430 left to work with?
Also, I told him to wait and see how everything runs on 8GB before he adds more RAM as he can just throw a couple sticks in there later on, but I may advise him to go ahead and get the extra 8GB if you all think it'll make that much of a difference.
