I have not built a computer in years. Just been buying OEM pieces of garbage. I currently have a HP made Pegatron Benicia 1.01 mother board... or at least that is what CPU-Z program says. It is running the E5200 Pentium with 4gbs of ram and a Nvida 9800GT. A newer game I have been looking forward to keeps crashing when a lot of things start happening, explosions, many characters running around, etc. I know my video card is fairly weak but I wanted to start by upgrading my CPU. I was going to make the jump to a core 2 quad 8300. Figuring that would make a significant difference. Will it make a biggish difference? Will my HP programed motherboard allow me to? (The specs I found on my board said it can handle it. I just don't know if HP has something that will not allow me to upgrade it.) Will I need a new heat sink/fan for the new processor or will the ones I have fit and keep it cool? ESD straps and arctic silver still all you need to install a new cpu? Sorry for the hundred questions I just want to be through.
