You notebook would blow away your desktop. The pentium M 2.0 Ghz is equivalent to like a 3.6GHz Pentium 4 Prescott. You have 1GB DDR2, thought the DDR2 might be slower than your current ram. You hard drive is definitely faster and the X600 isn't much faster than an 9600. So don't expect much better graphics.
question.......My new Laptop is on its way, hopefully I'll have it tomorrow. I'm wondering, will it be better, especially with games (I do some of that). Here are specs
ATI Radion 9600 256mb DDR
512 mb Ram
30gb 5400 hdd
AMD Athlon 1.2ghz CPU
ATI Radion X600 128mb
1 gb ram
2.0 ghz CPU
My Desktop has more video memory, but I'm betting the GPU is slower on my 9600 than the x600.
Any ideas? Both systems will run Xp Pro.
