will this computer system last me 2-3 years?

Ok so next year when I have like $600 to spend I'm going to build a gaming computer. the think is I need this thing to last me 2-3 years cuz my dad got mad at me for wanting to get a new computer just as we finished building my new one (I didn't really kno better and I got kind of out dated stuff, or hardware thats not ready for the futer of gaming). So I need your opinion on the system I'm going to build, ok here it is:

Gigabye:nForce 570 SLi,AM2,ATX,2pic-e, 3Gb/s SATA, DDR2 800 (pc 6400)

AMD athlon 64x2 4800+ brisbane 2.5GHz AM2

EVGA:8800GTS 320MB GDDR3 320-bit 96 unifide pipe lines, Im going to get an other GTS when games start to get reallyintence and graphicaly demanding and put then in SLi mode. then eventualy get 9 serise card or 10 (thats when GFX cards become 64 bit)

WINTEC AMPO:2GB(2-1GB sticks)DDR2 800 (pc6400)

HIPRO:700Watt PSU

Artic cool: freezer pro64 92mm, 40CFM, 900-2200RPM

western digital:7200RPM 250GB, 16MB chache

it will last you as long as you want it too as long as you like the performance it gives you you could go 3-4 years without upgrading if you wanted to no matter what settings you get in the future you'll always have better performance than any consoles out there so its just a matter of do you want the latest new stuff if not then it will last you this whole generation mastershake575

It will last you a good 2-3 years like predicted. I'd say you go with a Intel CPU if you want it not to be out dated as quicklytreytakahashi

You have a wierd avatar....everytime i see it im just like "what??.." no offense or anything though. :P

where did you heard AMD are "gaming processors"? does that mean they are only good for gaming?

Also you can get E2160 or E4300 C2D if you wan't budget CPU.
