I got the integrated t61 i see that the mobo has a pci express x16. Isn't it possible to connect a dedicated video card then? any thoughts? as well I have 2 GB of pc-5300 memory, is there any performance benefits if i plug in 4 gb of pc-6400 of mem or just 4 gb of pc-5300. meaning is there any way i can play with the mobo to get it to use the extra headroom.. i'm thinking of getting the T9300 core 2 also, for longer batt life etc.
