Extreme Noob Attempting to Upgrade Dell Precision 380 to High End Gaming Computer (Long term goal)

Hey, err, so I'm a computer enthusiast who knows very little about hardware. My ultimate goal is to turn this Dell Precision 380 into a high end Alienware or ASUS reminiscent computer. Problem is, I'm not sure what's compatible with what. So my first question is this: could I upgrade my single core Pentium 4 processor to something like and i5 or i7 without changing my motherboard?

 

Unfortunately, no. Core i3's and up use a different socket, ranging from 1155, 1155, and 1366. Your Dell supports socket LGA 775, which is an older socket supporting Pentium and Core 2 xxxx processors. The only way you would be able to install a Core i processor is to replace your motherboard. You're better off getting a new. What's your budget like?

 

Thanks for responding. My budget is on a spend it as i get it kind of basis. Could I get a good socket 1366 motherboard for around $200?

 

Np man. You can find great 1366 motherboard for under $150 even... This MSI board is really nice. Supports SATA 3, no USB 3 though...

One thing you should know, 1366 processors are around $250 and up. These processors were released around 2009 and have been succeeded by newer core processors, Sandy Bridge, and have socket number 1155. These are the latest processors with many new features incorporated into them. They are cheaper than the 1366 processors. If you're interested in these processors, check out this site for a list of whats available. And here you'll find special deals on motherboard and processor combos.

Tip - if you plan on playing some heavy games, don't settle for anything less than an i5 processor. i3's are for sissy's
