Well I would recommend the G73. I have the G72 and the build quality is great, performance is outstanding and the price for what I got in a gaming laptop was hard to beat. I play WoW on ultra settings with 8x AA & audio settings maxed as well and I'm getting 60FPS in SW (even after last nights Cataclysm launch). Don't know what sort of gaming that you do but Assassin's Creed plays maxed on it as well. The G73 should easily outperform my G72 (Core 2 Duo @ 2.88GHz, 6gb ddr2, 1gb GeForce GTX 260M)
the cheapest price is still around $1500, eh?
If you need something cheaper,have a look at Sager NP8690
