First Build for Gaming PC under $1000

Solution
Yeah, that build I posted all works together and has pretty good performance. The R9 280 will give the best graphics performance at that price.


So what would this improve? It is about $60 more.
I have no clue what any of this stuff is.
 
Get the r9 270 over the Gxt 750 ti since your build already has a PSU big enough to power it.

Video Card: Gigabyte Radeon R9 270 2GB WINDFORCE Video Card ($149.99 @ Newegg)

The difference is the graphics performance, you will get better quality at higher frame rates with the r9 270 over the gtx 750 ti. The only reason to go for the gtx 750 ti over the r9 270 is if you strongly prefer Nvidia GPUs (ie hate AMD), plan to use Nvidia's Shadowplay, or absolutely need Phsyx on your games.
 


Well my budget is $849 for everything except a monitor.
I want to have a good GPU that can play those games up top. im at $785. So i have a little room to upgrade. Any specific suggestions?
 
If you have $50 more then get the r9 280, that would let you play pretty much every game out at high or ultra settings:

IF you wanted to stay with Nvidia GPUs then this is the one to go with (but over budget by $20)
