Can I freely upgrade my CPU as long as it uses the same socket?

I'm trying upgrading my everyday desktop into a super-ultra-budget gaming PC and I want to be sure if I can upgrade my CPU with my current motherboad.

Current Specs:
Asustek P5LP-LE (Leonite) motherboard for Compaq/HP Desktop Computers
Intel Pentium D 820 2.8Ghz
GT 440 2 Gb DDr3
3 Gb DDr2
Windows 8.1

As you can see my CPU is pretty terrible, so I was thinking of upgrading to a Core2Duo E6850 which uses the same 775 socket.
Information on the motherboard: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c00864946#N74
HP states that I can upgrade to any Core2Duo E6- Model, though I want make sure it works by asking people with more experience.

This will depend on the boards FSB support, when the board was released the e6x00 series(ie e6600 e6700) had a FSB of 1066 and the e6850 was a newer cpu with a 1333 FSB. the e4x00 series of the time had 800mhz and bus speed of 800mhz

I am giving you this warning because some boards are not stable at 1333 or simply would just run at 1066(if that happens you get a Core 2 duo e6600 speed wise).

In normal assembled PC, it would work. But with OEM parts, you can't really tell.
First thing is check the MoBo's specs and check which CPUs does it supports.
If you don't find that info and you want to try (there may be some risks), install the new CPU and try to run your PC. If it works, there you have it.
If it doesn't work, reinstall the old CPU and upgrade the BIOS (is also risky) and try again with the new one.
If it still doesn't work, you're done. there's nothing else to do.

You should really, really consider doing a real upgrade. Change you're MoBo, CPU and RAM.
4GB 1333Mhz DDR3 is extremely cheap these days, $39 for a single 4GB stick or $45 for a dual channel kit, and, as you have been living with 3GB DDR2, I'm sure your performance requirements aren't too high.
AMD and Intel both have really good offerings in low end CPUs and Motherboards. A new Celeron G1820 has almost 5 times the performance of your Pentium D for $45. Also the low end MoBos are cheap, you can get a Intel H81 for $40.
And you can keep your GPU, because is still better than the GPU in the Celeron.

Well thanks to everyone that helped! I've decided to go with the Core2Duo e6700. It goes great with the GT 440 Graphics card. I'm well aware my MoBo is outdated, so I will also upgrade that in the near future to one that supports faster PCIe and Ram.
