@Haris4Real If your budget is little under $200, the get the gtx 950. Your gpu needs to closely match your monitor resolution, gtx 950 is known to work best with a 1080p monitor whereas the gtx 750 ti is best with 900p and lower resolution monitors.
@lemons22 Before buying my GTX 980 I've been running a 1080p display off my (overclocked) GTX 750Ti. It works. You can play most things on medium settings 50-60 fps, but I wouldn't recommend buying "old" hardware anymore.
@Haris4Real Do you think you can save up just a bit more.. like 20-30$ more? I'd really advise you to go for the GTX 960 which starts at 210$.
Reasons being: 4GB VRAM instead of 2, more power, nicely overclockable.
Well.. in terms of efficency NVIDIA beats ATI any day, although that might change with the new arrivals, but we'll see.
Generally speaking AMD ATI cards require more power and are weaker, but also quite a bit cheaper. For example: A GTX 970 beats a R9 380X, but the R9 380X costs 75 bucks less.
I guess in your case it'd be more of a R9 380 vs GTX 960
A 750Ti would be plenty for 720p, but don't you think you'll upgrade to 1080p
Don't you think the gpu comes before the monitor?
I've been thinking about upgrading to 2x 1440p and a second gtx 980, but no luck so far as I always run out of money before I can amass the sum that is 1300€ : P
But in your case.. I guess get the decent GPU first, then find some work over the summer (200 bucks oughta do the job) and buy a decently sized 1080p screen.. probably 27 inches if you can :)
