I'll list my current computer with extra parts listed at the bottom. I am not sure if the extra parts should be salvaged into a 2nd computer or sold to add money for other components or towards something else like another build or towards a laptop (something I've been wanting for a while). Here's the current build: P35 Gigabyte EP-GA-P35-DS3R Mushkin 4GB DDR2 RAM PC-6400 Audigy 2ZS Soundcard EVGA GeForce 7950GT Corsair HX520W PSU (modular) Samsung DVD Burner WD 320GB HDD Samsung 500GB HDD Extra components: Coolermaster 500W PSU Crucial Ballistix PC-8500 DDR2 2GB (2x1GB DDR2) Asus P5Q P45 mobo I was going to build a 2nd computer with the other components but I was wondering if it is a good idea to switch the motherboards and then sell the extra parts. For the P35 mobo, 2 sticks of RAM and the power supply, could I expect to get any decent return? What is the value of those parts? Or am I better off buying a used 775 cpu and building the 2nd computer? Why another desktop? Well, only because I have the parts already. They're not being used at the moment and possibly a finished system could also be sold, in theory? I thought of upgrading the video card and buying a SSD so then the current video card can be moved to the 2nd computer or also sold. Any advice/recommendations? I'm saving for a laptop but that's going to take a while and I do have a couple of laptops already but they're slow, older Thinkpad Centrino M machines. I'd like a more modern i5 laptop but I'll need to save up much more. I thought a SSD would make my current system faster and more responsive? Also, the video card is getting a bit old in the tooth although I'm not a hard-core gamer or anything. But, lots of this hardware is high on power consumption and I could lower it a bit with some new hardware? My other idea would be to sell everything either together or part it out but I thought that might be a bit stressful waiting to sell this stuff. I haven't done that before so I was hoping someone could comment on that. How successful have you been and did you get good prices/value on selling your stuff? I asked about buying a used 775 cpu in another thread but I thought my analysis of options has gone in all sorts of other directions (than just a used processor upgrade/purchase) and I thought I should post my own thread than crap further on the OP's thread. Hope that is an acceptable move. One final note: I'm impressed by the price/performance with decent temps/power consumption of the i3 and i5 systems. It makes me want one if I can't afford Sandy Bridge. I'm inclined to lean more towards an Intel system for that reason but I'm open to suggestions. Either to hang on to most of what I have or plan selling these components to upgrade. Thanks for any advice.
