I dont know about that. My budget was about 100$ (which i bumped up a little). All I really know for sure about graphics cards is that you should get an EVGA nvidia card :S If anything maybe try and find a PCI Express 3.0 card if your mobo supports 3.0 like this one maybe:
Scratch that i saw 2 for under $500 that were 3.0 lol, and they dont even have SLI support. The sucky thing about getting stuff that just came out is the low amount of reviews on it
You also might wanna get a different hard drive set up going:
smaller ssd + raid 1 TB drives
raid 0 ssd + raid 1 TB drives
This would give you more disc space, cost less, and give you the peace of mind of redundancy. constantly writing to your ssd will kill its life span dramatically, especially if it is your only hard drive.
