old cards to new on benchmarks is always annoying. you can usually find benches 1 gen up, but not much past. So i found some charts showing that 2x 560TI in SLI is pretty close to the performance of single a gtx 680 depending on how the games scale with SLI. and a 680 i can translate to current gen a 960. So that's close to what you have right now. So you need to go above that, you would want a 970 to get an upgrade. Sadly the 970s still run over $300
However, you have a pretty sweet option here. Go second hand! The 780 are a full 1:1 with the 970 in most benchmarks.
Hit up ebay and you can find a 780 (non-ti) for about $250-275. that would give you a good 25-30% boost from where you are. They are 3GB cards, so while not as awesome as 4gb ones they still do just fine for surround. I have a 780ti 3gb and it's fantastic.
As for your question about DVI, it's getting pretty limited on modern cards, i have 2x DVI ports, 1x HDMI 1x Display port. But cards all vary by make/model. so even if you got a 780 you would need to check the ports on the back depending on who makes it. You can convert DP and HDMI to DVI without much hassle though, you can get adapters and/or cables cheap on amazon.
