GFX Card suggestions for rendering

[ChetzB]

Hi all, I know I've asked this before.

Previously, I had a GTX 460 1GB which rendered relatively well in Vegas Pro 11/12.

Since asking about a new graphics card for rendering/gaming, I was suggested the HD Radeon 7850, which does a nice treat when it comes to gaming. However, Vegas isn't about to utilise the graphics card to help with rendering.

My question is, say with a budget of £200 (£250 would be pushing it), can someone suggest a graphics card/a few, that are cable of being used in line with Vegas to help previewing and rendering?

Thanks

My system at the moment:
Power Supply: XFX 650W Pro Power supply
CPU: Intel Core i5 2500K 3.30GHz @ 4.60GHz Sandybridge CPU
Motherboard: Intel Z68 (Socket 1155) DDR3 Motherboard ** B3 REVISION **
Graphics card: MSI HD 7850 Twin Frozr III OC 2048MB GDDR5
Cooler: Corsair H50 CPU Cooler
RAM: Corsair 16 GB Vengeance 240-pin DIMM DDR3-RAM 1600 MHz
Hard Drive: Western Digital Caviar Blue 500GB SATA 6GB/s

I'm new here, but what about the 660ti? - It's in that budget and is pretty hefty, my friend uses a 560(I think) in vegas and it does well, he's looking at moving to a 660/670 shortly. I myself do 3d renders in CAD and am planning on a 670

I think a 660ti would do the job.

Yeah, 660ti.

It's almost a shame really, I went for the 7850 based on suggestions here in another post I made >_<

Originally, well, at the time I planned on going for the 560ti.

Need to find out if anyone fancies having a relatively new 7850, or see if something could be exchanged :/

Appreciate the suggestions everyone

A 560Ti should give better performance with compute tasks than a 660Ti.

If I were to go with one out of the following three, which would people recommend?

MSI GeForce GTX 660Ti Power Edition 2048MB GDDR5

KFA2 GeForce GTX 660TI EX OC 3072MB GDDR5

OcUK GeForce GTX 560Ti 2048MB GDDR5
