560 ti sli on 650w?

[Widz]

I have a

i5 2500k

Thermaltake frio (it was free, so I can deal with it)

P8P67 Pro

4GB Corsair 1600mhz

EVGA 560 ti

Corsair 650W TX

Now I was wondering if I were to buy a second 560 ti down the line, like when BF3 comes out, would I need to buy a new and bigger psu, or will the my current 650W TX be good enough?

I think it would be a struggle on a 650watter tbh dude Id be inclined to say 750w should be a minimum for a pair of those and a decent spec'd system

so my best option to either buy a bigger psu and a 560 ti, or when the time comes, sell the 560 ti and use the money to put towards getting like a 580 or a higher end single card?

Buying a bigger PSU will mean you aren't restricted as much with upgrades like this in future.

Bigger PSU would be better to get as you already have a 560.

bigger psu have it's advantages.

1. scalability

2. fan won't run loudly if it doesn't run at full load.

3. bigger psu have the ability to degrade as time goes.
