It's not that I don't want to replace all of my system, I do, it's just that I have to go slow and buy parts each week.
Right now, with just that 760, I'm able to run AC:Black Flag at max/high settings with decent framerate @ 1080p. I'm actually happy with it overall, I thought the CPU would hold it back more but it runs great!!
Anyways, yea, I do want to replace the CPU/MoBo and was thinking about getting the i5-3470/3570/etc., whatever you guys recommend. What's so special about z75/77 chipsets? Can't I just get a cheap mobo that supports the socket-type?
Hey, that's great news. So in the meantime, it seems you are fine. Now, for an upgrade, I suggest that you set money aside in a fund until you got about $300 or so to buy the MOBO+CPU+Win7 together. Watch those newegg deals. Usually, you will find Win7 for $80 or else they go over $100 on newegg.
The more expensive mobos have more features that you probably don't need, like better overclocking support. You're limited to mATX boards. The prices vary depending on what you want on the board. If you go with 2 RAM slots and no SLI option, you can get good quality boards $50 or under. If you want 4 RAM slots, prices start around $60. The i5-3470 is around $180 so the only place you can cut back on is the MOBO.
You might be able to get everything you want for $300 but be prepared to go up to $350. For the time being, it looks like you're good to go.
