I don't have the money to make a new system and only option is to upgrade my current system. I am thinking about upgrading my e5800 to q9550 or any q9xxx really. My system has no oc ability (greyed out in bios). I have a nvidia gts450. I am wondering if I upgrade my cpu it will give me better multitasking, engineering software, and gaming abilities (per/$ wise). I am thinking about buying one used off of ebay to get a one around 100~150.
I know I have an earlier similar post, but the more I am reseaching the more I am thinking that it would be a good investment. I have checked all the benchmarking comparisons, but I know that benchmarks and irl are two different things. I am also concerned about bottlenecking (although I have seen this is not a problem with my gpu). thanks for your help.
