Which one of these GPU's are better?

[lichon]

I am new to the PC world, and I recently built my first PC. I was wondering if the ATI HD Radeon 5700 1gb, ATI Radeon HD 5870 or the PNY Geforce GTX 650 2gb was better? How can you tell? Thanks in advance!

The gtx 650 should be the best. I can tell based on the launch reviews and benchmarks.
