I'm having some trouble finding a good graphics card (there are so many!) and am hoping someone here can help.
I'm looking for one that will play games like Diablo 3 and World of Warcraft smoothly; according to Blizzard's website my computer should handle them well except for the graphics card which is apparently horrible.
From reading other questions it seems that the only determining factors for a compatible card are motherboard and power supply so here they are:
Motherboard: ECS A880LM-M
Power supply: Allied ATX 400W, model number SL-8400BTX
I don't know if you can get a good card for around $100-150 but that's what I'm aiming for.
It doesn't look that your PSU has a 6 pin cable to power strong cards. I think you should go with a GTX 750 which totally fits your budget and should work with your PSU as well. And upgrade to a quality PSU like Corsair CX430 would be also useful.
The 260 is a little shy in psu requirements by approx 50w but will still run ok IMO, the 750ti is spot on.
The 750TI has:
Higher pixel rate 33.06 GPixel/s vs 17.6 GPixel/s Around 90% higher pixel rate
Higher texture rate 82.64 GTexel/s vs 61.6 GTexel/s Around 35% higher texture rate
Higher clock speed 1,100 MHz vs 1,020 MHz Around 10% higher clock speed
Higher effective memory clock speed 6,500 MHz vs 5,400 MHz More than 20% higher effective memory clock speed
More shading units 896 vs 640 256 more shading units
Slightly more texture mapping units 56 vs 40 16 more texture mapping units
Higher memory clock speed 1,625 MHz vs 1,502 MHz Around 10% higher memory clock speed
