I recently upgraded my computer with a new graphics card, an EVGA GT 240. I watched videos of people playing Crysis 2's campaign at extreme settings, and I also see them playing the Multiplayer with no lag. For me, campaign runs fine, but multiplayer lags like crazy unless I use the custom graphics settings. My computer has 2GBs of RAM and it has an i3 dual core processor at 3.00GHz. I think I need to upgrade my RAM. Any feedback? Thanks.

First off all, My CPU is fine. 3.00GHz is plenty to run Crysis 2. SECOND, I've already played it on high and it works fine, and everyone I've seen play it on this card has either the same or LOWER CPU speed, like 2.2GHz or 2.4. It is not the CPU. THIRD, I DO expect max settings considering my GT240 is factory superclocked. My resolution is currently 1280x1024, until I upgrade to a new monitor. I'm 99.9% sure that I just need more RAM.
You won't get max settings with a gt 240, even at 1280 x 1024
Factory superclocked on such a low end card means nothing. By far, the most important factor is the number of CUDA or shader cores in the card. Your gt 240 has 96 shader cores. The latest top-of-the-line GTX 680 has 1536 shader cores. 'nuff said.
The clock rates does make some difference, but overclocking usually raises it up 20% or so max. You can't make a 240 max crysis 2 because there is no way overclocking can't make up for the relatively low number of shader cores.
You should look into a card with more cores like the GTX 560 (336 cores and running at a higher core clock than the gt 240) or a Radeon 7770.
Just lower the settings, and don't expect to max out crysis 2. I've got GTX 560 Ti, which is far more powerful than your GT 240, and I still cannot max it out. It's just a game that isn't meant to be maxed out.
OP: 4gb or even 8gb of RAM would help. 2gb on a modern system - and I assume running Windows 7? - is just terrible. I have lots of RAM, and just Windows alone uses just under 2gb. With only 2gb... well, yeah, that's going to hurt. You can buy cheap 2x4gb 1333mhz RAM now and I suggest you do that. If you only have a 32 bit Windows version, then you'll be limited to 4gb. Not sure but you might be able to reinstall it as 64 bit.
After that the GPU is pretty slow. Just a 6770 would be a massive performance boost.
An i3 isn't a bad CPU although it depends on which model. Is it the i3 540? What motherboard do you have? A future upgrade to an i5 760 would be awesome if you can - although you'll have to find it used most likely (ebay or kijiji).
