Hey there!
My main system is a i5-3570k with a gtx 480 and 8 gigs of ram. Plenty for what I use, 0 complaints, 0 fps drops on any game. (Except maybe WoW occasionally in intense raid moments)
Tonight I just got a free system. It has a i7 860 Lynnfield series process with a GTX 5770 and 8 gigs of RAM. The only thing is it came without a hard-drive.
I'm going to get a 500 GB SSD for my main system and take that mechanical and put it into the i7 system, and that's perfectly fine for me. I'm going to use this computer as a fun second computer or (more than likely) have it as a spare gaming computer for my girlfriend who lives with me or for any friend who comes over and wants to play some type of game.
The system hasn't been tested in any game. I'm not 100% sure how well it'll work, because to *my* knowledge, this processor is just a tad bit better than a phenom x2 series processor. I had a 955 and I got *some* FPS drops when playing CS:GO and WoW, but I also had a HD4850 at the time.
ALL OF THIS HAVING BEEN SAID... Would it even be worth it to upgrade the video card, the 5770? If so, what *should* I upgrade it to? I know I shouldn't put in any series that's a GTX 500 or more (unless cheaper than any generation before) because it'll probably just bottleneck. And when I say "I know", I mean "I'm pretty sure."
Anyone have a cutoff for what to upgrade it to? Would it even be worth it potentially?
