upgrading dell 960 from core 2 duo to core 2 quad intel q9400

[Cletus_3]

i have a dell optiplex 960 sff. it came with i believe a q8400 core 2 duo processor . i removed it and put a intel q9400 in it's place.so i put it back together and turned it on and it works great . but it just doesn't seem as fast as it should be . so i added 4 more ghigs of ram ddr2-6400 . all 4 are the same brand infinity i believe without looking . so , that made it a little faster . i installed a fresh copy in windows 7 ultimate 64 bit. it came with a desktop 80 gig hard drive . so i added a 40 gig hdd to it . of course now i have 120 gigs of hdd.i formatted the 40 gig and just left it blank. so i have almost 40 gigs reserve. anyway . they computer still seems to not be as fast as i would think it should be with 8 gigs ram and quad cores . is there a bios upgrade for the dell 960 i need to install or something for the processer ? if anyone knows i wouls really appreciate some advice . i know a lot , but this one has me stumped , thanks in advance for any and all assistance and have a great day .

It doesn't seem as fast as it should be...in what? That description is so vague it's useless. Question, did you run any kind of benchmark yet? Are you just clicking on things on your desktop? Have you verified that the CPU is running at the clockspeed it is supposed to be running?

Are you using the cooler from the core 2 duo? It could be getting too hot and throttling.

Also, old/low capacity hard drives tend to be slow and wont load things so fast, it may be a good idea going for a larger/newer HDD or getting and SSD.
