Pentium compatability

I want to know if older socket 775 Pentium processors are compatible with current motherboards. what I would like to do is grab say a Pentium D 950 (3.4GHz 800MHz FSB 2x2MB L2) CPU and put it into a current Pentium dual core motherboard.

I'm pretty sure the memory interface is on the northbridge and not the CPU so I would expect this processor to work with DDR3 memory.

hypothetical setup:
Biostar G41D3C Intel G41 Socket 775 mATX
Pentium D 950
4 GB DDR3 1333 (dual channel)
AMD Radeon 6450
decent power supply
SATA 300 160GB HDD

I know this motherboard supports my FSB (aong with many others), my socket, and I think it supports my TDP so I can't find anything wrong just from the specs for compatibility.
 
Not sure if you found what you were looking for but I have a E3400 and an EVGA GT430 for sale. I'll sell them both to you for $70 shipped.

- E3400 (2.6ghz, 1mb cache, Core 2 Duo)
- EVGA GT 430 (Fermi) 1gb GDDR3

Note: Both of these items are just about a month old... Never really ran the E3400 in my rig as I had a E5300 to replace it... The video card however will run pretty much any entry level game you through at it (when I say entry level, I mean counterstrike 1.6, counterstrike source, guild wars, heros of newerth, all on the highest settings on 1366x768. Games ran flawless on the card with my OCed E5300 @ 3.25ghz (same specs as e3400 but 2mb L2 cache).
