prole and i discussed that very model on a past borecast
i own the G50VT-X5, it is great, runs fallout 3 at ultra settings, COD5 at max, L4D at max, crysis and crysis warhead on medium (turn down shadows)
i don't know if you'd ever want to do it, but the processor and vidcard are upgradeable
it's garishly ugly, that's about my only problem with it - also, don't make the mistake of buying a 15" carrying case/bag, it's bigger than normal 15" laptops, you're gonna have to get a "17 case/bag
that's $50 cheaper than when i bought it, too
basically, you are not going to find a better gaming laptop for that price
