Hi I need an opinion on a Building a computer. I have a intel e5700 proccessor which I bought it some time ago to upgrade my old proccessor. However it couldn't work so I kept it. I was thinking of building a system using that proccessor. But would it last for at least 2 years? By the way, I am doing some mainstream games like mordern Warfare 3 and crisis 2. I have another choice Which is to build it with a core i5 CPU that requires me to spent extra cash on it? Either way I need to buy a new motherboard for them. The system I wanted to build contains a gts450 graphics card an a 550w psu with 3 to 4 gb of ram. Please feel free to give any suggestion. Even if it is a different category or things that I've not listed. Thank you for all you help.
