Hello, I am new to tom'shardware but I am very impressed with everybody's knowledge!!

First of all I would like to say sorry for being poor. I would buy a new system but I just graduated college and don't have the money right now.

I have a Dell Vostro 200 which shipped to me on 2/27/2008 so it's almost 5 years old

E4500 Core 2 Duo 2.2GHz L2 Cache 2048

I have 4 Memory Slots with a maximum of 4096 DDR2 SDRAM 800MHz (PC2-6400)
I have 2 slots with 1GB DDR 2 and 2 slots with 512GB DDR2

My Video Card is an XFX Nvidia 8600 GT 256MB DDR3 680MHz

Two Questions:
Would I see a noticible difference going from 3GB Ram to 4GB Ram?
Would I see a huge jump from my Nvidia 8600 GT to ASUS HD7750-1GD5-V2 Radeon HD 7750 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card ?

I know my PCI Express X16 can't take advantage of the 3.0...

Basically I am wanting to know if I will be able to play Company of Heroes 2 if I upgrade my video card and the ram. If not Please let me know if I would be wasting my money. Company of heroes 1 works perfectly on my system with high settings on a 1980x1200 monitor.

If I decide to save for a new rig what is the best Bang for your Buck Rig under 700 bucks... I'm not too concerned about what graphics card is in it as I can always upgrade that.

Thanks so do you know if RTS games like XCOM Enemy Unknown, Starcraft II, or Company of Heroes 2 are CPU intensive or GPU intensive? If my rig can play those games if I upgrade the GPU and add 1gb more ram then I think I'll go that route and wait for Ivy Bridge CPU rigs to drop in price. Like I said I can play Company of Heroes 1 on full settings on a 1920x1200 Resolution. Granted that game is about 6 years old. I can play starcraft II on low settings. Is there a way to tell where the weakness lies by observation?

Basically is the upgrade from the Nvidia 8600GT to the AMD 7750HD a huge jump? Will that fix poor frame rate or is frame rate a cpu issue?

Thanks! I guess now I'm considering cost... If I can play the real time strategy games I want with the 7750 and adding 1GB Ram I can do that for about 120$ If I get into a CPU upgrade I may start looking at too much money... unless the E4500 Core 2 Duo 2.2GHz can be upgraded for cheap I'm just not sure what would fit the mobo and what is the best upgrade if the faster core 2 duo cpus will fit.
