Currently using a Pentium4 3GHz (Stock) CPU Intel Augsburg D915GAG (Stock) Motherboard 2.5GB RAM EVGA 8800GT Of course im considering in upgrading into a DUAL-CORE cpu to get more outta my GPU, but will i also have to get new RAM/MOTHERBOARD? or can i just get a dual core that will work with my MOBO? Here are the specs for my mobo chipset: http://www.intel.com/products/chipsets/915g/index.htm Says its "LGA775" Socket which should support any C2D out there cause they all have LGA775 sockets. Shows that the Intel 915GAG has a 800/533 MHz system bus. As almost all of the DualCores/C2D's have 1000+MHz FSB. Ive found two C2Duos the E4600 and the E4500 that are running @ 800FSB - LGA775. (link below) http://www.ncix.com/search/?categoryid=2-106&q=800FSB Does this mean it would be compatible with my MOBO so i wouldnt have to buy new RAM/MOBO to go with the CPU? Thinking my only option to get a C2D would have to get a new MOBO and RAM also, but now im not to sure if i need to. Would be great if i wouldnt need to and still grab the E4500-4600. Would still be twice as better than my current P4 right, without spending extra for new MOBO+RAM.
