Budget? ......................You probably dont need to much if you are not gaming. Games are what will drive up the cost of your build.
I am building my first computer & I'm having trouble deciding what processor (AMD Phenom II X4 965 or the Intel i7-870 or 950) & what type of RAM (dual vs triple channel corsair XMS) to use. I don't do gaming, & I use it primarily to do schoolwork, internet browsing, stream movies, watch videos, listen to music, & manage/edit photos. Any suggestions would be greatly appreciated!
+1 to embra. A budget is a very good thing to have when selecting stuff.
Although the cpus your looking into is really wasted money on what your doing. Reason for that is, there both over powered for what your requiring.
I would just Recommend the Althon II x4 as it still a quad core. So its still a good long term cpu to have but it's about $100 or Go for an tri-core Athlon II x3 cpu for roughly $75. Even though there slightly weaker cpu's, for what your doing, you wouldn't notice the performance loss.
With Ram, just go with dual channel. (kind forced to go dual channel as only the Consumer desktop chipset is the intel x58 chip that has triple channel.) Triple channel, unless your running cad or something thats needs lots of memory/memory bandwidth, is not worth it.
4GB is the current sweet spot for computers right now so that all you have to spend your money on.
