Gtx 560

Im considering the GTX560Ti TwinFrozrII-OC from MSI to replace my going 3yr old GTX285 and I would like to ask is 1Ghz core clock pretty easy to achieve with a minor voltage bump using software?

After back reading seems that 1Ghz is not that achievable but 950Mhz seems to be pretty common, this card also has great potential in SLI as ive seen on the hardocp review and other sites as well.

BTW does the MSI Twin FrozrII-OC oc better than the Palit Sonic or its all about the luck of the draw?

The OC-headroom seams to vary a lot, much more than typical GPUs. It looks more like Intel's Batch# variations.
Some partners seams to be cherry picking good chips for factory-OC models, so if you want a guaranteed 1GHz, then you should get a GB SOC.
On the other hand, this cherry picking will increase your risk for a dud-chip if you buy a stock/OC model from GB. The same may apply to others too, tho.

So I guess, either buy the highest factory OCed model from those who cherry pick, or buy from those who doesn't cherry pick at all. It's not easy to know who is cherry picking or not, so in this case, buying form partners who doesn't have a factory OCed model would increase your chance for getting a better chip.

I personally would go for GB SOC tho, it doesn't cost much more.
