These are two cards I'm looking at to upgrade from my 1GB 6670, which is better price/performance with minimum known overclocking? All feedback is appreciated

Get the MSI 660, I have one and they are amazing especially for that price. Also they are better than the 7850, often compared to the 7870 as the close AMD card.

If you go with the benchmark used on videocardbenchmark.net you get:

7850: 3707 / 119.99 = 30.89 ?/£
660: 4111 / 143.59 = 28.63 ?/£

So the ATI has a better performance/price. According to that benchmark.

Edit: Someone pointed out the 7870, so let's have fun with that. The cheapest one on scan.co.ok is 155.74, and the benchmark is 4243. So we get 27.24 ?/£. Apparently the faster the card the worse the performance/price ratio. The cheapest geforce titan is 10.29 ?/£.

Thank you for your responses, also if anyone knows of anywhere i can get either of these cards or better for cheaper/around the same price that would be very helpful.

Thanks, i have literally just found them on pc parts picker and bookmarked them :L btw, i've heard that although physx with the 660, although will 'enhance the gaming experience', will reduce fps in the few physx supporting games, is this true? If so i think that means an AMD card for me...

Also, if i were to upgrade, can anyone suggest to me some good quality, cheap PSU's that are at a minimum 500w? 80+ would also be a bonus, thanks

Hi - oxymoron on the PSU - "good quality and cheap" isn't really probable
on PSU's, what is your budget for a PSU?

This is your best bet quality/price wise:

You can turn physx off if it's lowering your fps.

djlolly42 · Aug 7, 2013

That PSU would be great, £50 would be a maximum tbh, but with regards the physx, is it true with what i said? That having physx enabled reduces your fps?

djlolly42 :

Usually yes, the GPU has to do more work to do the physx calculations. So unless the GPU is overkill for the game you're playing so it has processing power going to waste, yes physx would lower fps. ATI cards don't support physx so they don't have to worry about it. But like I said, if you're worried about that simply keep physx off.
