2000 on a laptop?... basically a portable media player with a word processer . as xfodder stated , get a mac if you must get a laptop. and tweak the fucker out
as for main pc , best to ask when you got the cash in your hands "prices change very fast"
7800's are quite nice , all the ones i have used in the last few pc's i have built have worked well "SLI for the win" tho they run quite hot , even in a case with fans to the hilt . 7900's id stay away from , we had a bit of trouble with them and the price is nasty .
I also had some minor problems with the top end ASUS mobo's , a bios update fixed it tho , they have trouble with sata hard dives .. "data errors " but as i said , flash the bios and alls good .
id recommend spending the extra $120 on a good power supply, especially if your putting some heavy load on it , last stock psu i got spat 2 feet of sparks out the vents on the back of it when i tryed the first boot
. and another top end thermaltake psu we got for a dule core sli comp filed the room with smoke in about 2 mins due to a factory fault "anidised coating smokes up good .."
anyways i could rant on more but as i said , let us know when you got the cash .
