new rig after 22 july

i am going to build a new pc after 22 of july i am going for q6600 striker extreme mother board and 2 gb DDRII ram with 8800gts 320 mb the problem is that i want an lcd monitor and the ones i have available here within my reach support a resolution of 1280*1200 but all the reviews for these components are done on atleast 1600*1200 resolution i wanted to ask you that is my monitors resolution that bad and if i get that monitor and play games at the given resolution how long will my rig last

They key thing about resolution is that the higher your resolution, the more powerful your video card needs to be. 

Hypothetical example: You might be able to play Crysis with max detail on a 8800GTS at 1280x1024, but need 2 in SLI to run at 1600x1200.

Thanks man and how long do you think my components will last i dont mind playing games on medium settings and at 1024*768 resolution what really bothers me is the upgrading of pc i want it to last very long like 3-5 years after that i will build a new one thanks in advance
