New gpu?

[Nevakonaza]

So i might be needing a new GPU as i think my 6950 is dead.

I was considering either a GTX 560Ti 2GB OR GTX 480 1536MB. as they are around the same price range give or take.
choose the 2gb 560 as i have 1920x1080 monitor and would like the extra memory.

Although im im a bit concearned that if i go with the 480 if my psu will handle it,AND what sort of heat the 480s gonna kick out.

my psu is this

OCZ ModXStream Pro OCZ600MXSP 600W

- 150 x 160 x 86mm (W x L x H)
- ATX12V v2.2 and EPS12V
- up to 86% Efficiency
- Overvoltage/OverPower/Short-Circuit protection
- (.99)Active PFC
- MTBF: 100,000 hours @ 25C
- 1 x 20/24-pin ATX

- 1 x 4-pin CPU
- 1 x 6-pin PCI-E
- 1 x 6+2-pin PCI-E
- 4 x Peripheral
- 2 x Floppy

what would you go with? 560 or 480
