Best card for Asus P6TD Motherboard

[Laben]

After about 5 years, my BFG Tech GTX 275 sputtered and died; most likely due to overheating, wish I could find out for sure.

Needless to say, I need a GPU replacement but I am also very much behind the times insofar as the GPU market is concerned. I only just discovered that BFG Tech is no more, in fact.

What I'm looking for is the best video card I can buy for my motherboard with the least amount of diminishing returns. I do game but I spend vastly more time in Photoshop and 3D applications. Advice from the collective wisdom that is Tom's Hardware would be most appreciative.

My motherboard is an ASUS P6TD which has a PCIe 2.0 slot (http://www.asus.com/Motherboards/P6TD_Deluxe/). Installed is a i7 920 CPU with a Corsair 750W supplying power to the rig.

Thanks in advance.

The current system is still plenty powerful as you probably know and the GTX275 is, by current standards, quite weak: http://www.tomshardware.co.uk/gaming-graphics-card-review,review-32899-7.html
With the installed power supply and motherboard you can actually pop in just about anything you heart desires with little or no restrictions from the venerable i7 or the PCI-E slot.

Probably the best budget option would be a GTX750Ti, it's a good part and practically sips power, while being a decent upgrade. The dual fan coolers aren't really needed but they do keep it very, very quiet.
More cash to spend? Move up to the GTX960 class, (it's not in the chart but sits around the GTX670 level).
The AMD options in each performance tier are usually a little less expensive but require more power, produce more heat and can be nosier but also have more Direct Compute and Open CL muscle, which should help out with your Photoshop uses.

Serious cash burning a hole in your pocket? The GTX970 is a massively potent part, and carries a >$300 price tag to match, while its AMD R9 290/290X rival is less expensive it does demand a very good cooler and plenty of case ventilation to keep both the temperatures and noise to reasonable levels, and the triple fan coolers are very large (My Tri-X R9 290 is 12" or so long).
