Upgrading from a 7750.

Since my power supply is junk lol. My new plan is to now pick up a new power supply then grab a radeon 6950 or 7850. Still not 100% yet on which is the better card I'm getting mixed feed back on them.
 
I did some calculations on your PSU and after derating and apply the design standard, it would be lucky if that PSU could provide 13A to your graphics card (160W approx). Not enough for the 12V rail minus the CPU. Remember thats when it shuts down too (assuming it can provide what it says on the tin which it probably cannot).

The CX600 is a good choice. Im glad i pushed you to look into that, it couldve been nasty ;)

I'd get this TX650 by corsair which is $70 after rebate etc.

And this GTX570 which will smash both of the above

All for about $340. Great step up for both quality and power.

If you wanted to keep it closer to $300, then the CX500 is $50, but you will have no head room for upgrades like SLI (you will with the TX650).

TX650 would be nice to have for future plans of SLI. I did some looking at the 570 it is better than both but not by a huge amount but still nice none the less. Well looks like I have some orders to place. Just one more thing the mail and re-bate expires in 2 days lol but it's only $20 not really a deal breaker.
Thanks again for the people who helped me out. I would have most likely screwed myself over without it.
 
the mail in rebate deal expires in 2 days, but you have about 20-30 to postmark it, that just when it is no longer offered to anyone, and it will instantly be replaced by another rebate which is probably the same deal. And truly the 570 will be better, they have better drivers and they do better at some things because of their cuda cores which are great at work applications
 
+1 on the gtx570, if we're looking at bf3 performance in particular. I believe based on looking at the case of the game that it's optimized specifically for nvidia cards, so you've the best chance of maxing it on med or high using that card. Don't use that power supply though, i'd use a higher quality one from Corsair/Seasonic/Silverstone/Antec/XFX. Use a wattage calculator before shopping to determine the exact wattage necessary, and also look for things such as active pfc, amps on 12v, 80+ gold, modular cables, warranty, and volt protection.
 
I agree, the 570 is a beast and will own BF3 like theres no tomorrow. As for PSU, same advise as above by Russ. I'd still recommend Corsair/XFX or even Nexus if its available

So for a single GTX 570 would the Corsair CX600 cover it or should I just use a TX750?
 
600 will do fine for a single, if you want to use 2 later on then i'd get the 750, looked on newegg and this is only 16 more than the tx750, but rebates down to 1 more than the tx750 rebates to, and has more power, so i'd get it if you want to sli later on, will give you plenty of overhead, you might be able to squeeze 3 570's on here, not sure though, but that's if your motherboard supports it. What is your motherboard? it might be able to sli at all.

The 570 will rape anything discussed previously and the TX750 not only has significnatly more power it is much better quality PSU allowing for future SLI considerations. It also comes in a semi-modular version - which i reckon is worth the extra $5.
