Doesn't the G53SX have the 128-bit 560M? :/
Kepler/IB system will be a lot better. What's 2 months, really? 40nm GPU are soo 2009, so to me if I didn't need something right now, waiting 2 months to have bleeding-edge tech instead of a 1-year-old CPU and graphics on a ~2.5 year old process size.. sounds like a good idea. What's the worst that happens? 660M is as fast as a 560M but uses 30% less power? Realistically it'll be more like 650M is at least close to 560M performance (maybe a little slower), and 660M is as fast as a 570M, and so on. And the IB mobile CPU clockspeeds are already released, 3.4ghz quad-core turbo sounds a lot better than 2.6 (or is it 2.8ghz) quad-core turbo from SB.
Lol if you think Kepler will only be 10% faster. The OCing is insane on 28nm, if nothing else. I'm not a big Nvidia fan but their graphics will bring it, and there's always the possibility that more laptop makers include Optimus on this round of laptops.
