GPU or e-GPU

The m15x cannot do optimus and I highly doubt it can do x2. The ports are also running at the PCI-E 1.1 2.5gts rate. Getting a new dedicated is the best option. Unfortunately dedicated cards are very expensive. The 7970m and 8970m while cost effective, draw too much power for the laptop to handle when overclocked. I'd go with a 675mx or a 680m. The 780m is a possibility but that has power draw issues when overclocked as well, so it's not really worth the extra cost.
