i meant the 1gb or the 512 mb video card, the ati radeon hd3650gamer4life73

It depends on the size of your monitor. If you only have a 19" monitor then there is probably no need for the 1GB version. Especially if the 1GB version is more expensive.

No, I don't think that will work. Because it is a 240-pin module, and not a 184-pin. Newegg has better prices than tigerdirect. Heres a link,

Oops, didn't realize you posted your model number. So i ran the ram configutator, here are the results...

so how do i kno if the memory sticks will be compatible with my comp?

Ok, so what you need to find out is what kind of Ram your motherboard supports. There a few different ways that I know of. First, if you know your computers model number and such, then this tool on this site will help you find the memory you need. http://www.tigerdirect.com/applications/category/category_tlc.asp?CatId=10

Or, you could download this

http://www.howtogeek.com/howto/windows-vista/what-kind-of-memory-does-my-computer-have-installed/

The first option is best. There should be a link on that site saying memory configutator.

I would reccommend building your own. But if you aren't comfortable with that, Newegg has some good pre-built computers on thier site. Like this one

That computer will not run any modern games, let alone Crysis. I did find a couple of other computers though that might suit your needs. I don't know what your budget is but this computer is 5 bucks less, and a lot better.

With this computer you should be able to play at low settings. I had an geforce 8200 graphics card before I bought my 9600gt. And I could play the Crysis demo on super low. At a fairly decent frame rate. This card might do a little better, but it won't run any new games on high. However, it is much better than gforce 6150.

Another option is this...

Again, this isn't top of the line, but it has a 9500gt in it. Which is pretty good. I have a 9600gt and I can play Crysis with a mixture of high/very high settings at a playable framerate. A 9500gt should handle it on medium. Of course, all of this depends on your budget, and if you are willing to build one yourself...
