Considering my motherboard has a single x16 PCI-E slot(the other one being only x4 in speed), this would be a good choice to replace my 8600GTS... Since it(theorically) has the power of two cards, in a single slot.
Mine would be Professor Layton and the Curious Village, it has challenging puzzles and a good backstory to support it. I'm currently trying to find all hidden hint coins... Man, that's hard!
