$7 each Scythe (Get 2 of these soon)(can only mount 2 in the rosewill case)

Pick up a better PSU, and vid card later (PCIe-2.0).

Well as you have a spare case, HDD, I feel you will be happy with these options...

CPU + Mobo combo...

RAM-

The Geil is gud...but just for $2 more, better off buying a RAM with heatsink...
The onboard graphics is the most powerful available now...It comes with 128MB sideport RAM for graphics...And the 7750 is the a very gud dual core...

Gkay may be unwilling to spell "good" properly, but the components he has listed will be better than IH8U's (which aren't all that bad either). The HD3300 graphics on the 790GX are another tier higher, and the CPU is much better than the 4850e.

Thanks for the replies. I still have the dilemma about upgrading vs. new cpu/mobo. When I look at the integrated gfx on those boards, the Radeon 3200 is right about on par with the 6600gt I'm used to, at least according to the hierarchy chart on here (right?).

I like that the suggestions give me better graphics options in the future, but would I be better off just buying something like an AGP Radeon HD 3650 for what I've got, and pushing out the total system upgrade until later?

If that's what you want to do. The 3650 would certainly be faster than the 6600GT or the onboard 3300 of the 790GX. Still your system is pretty dated. You could build a better system by using this

ASRock A780FullHD $56.99
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

AMD Athlon 64 X2 5400 Brisbane BE $57.99
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

OCZ Vista Upgrade 2GB (2 x 1GB) DDR2 800 $22.99
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

SAPPHIRE 100248L Radeon HD 3850 512MB $59.99 if you buy it now
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

And that comes up to $197.96. Compared to your current system it's a screamer  . of course that 3850 fluctuates from 59.99 - 74.99. I'm thinking of getting one next month to xfire my current Asus 3850, but the price changes like every 2 days, so if they raise the price back up again you could instead get this 4670

SAPPHIRE 100255HDMI Radeon HD 4670 512MB $64.99
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

And that would be a total of $202.96. Either way it's not a bad system and you can overclock that 5400 BE. The ASRock A780FullHD is a great board, and while it's great for overclocking if you know what you're doing it's not too newb friendly for it like the Gigabyte boards tend to be. Of course, always read the sticky before overclocking to understand what you're doing and you'll be just fine  .

As I had said earlier, good can be spelled as "GUD" also...

That may be true if you use shorthand, but is it really that much harder to type an extra "o"? Most people on these forums prefer to read proper English, not shorthand.

Ohh... very well short I mean shortstuff...

Ahh...but I still don't get it...why you people cant get over it  

We aren't used to shorthand when it appears sloppy. Pick up ANY newspaper or magazine (or book), and despite the plethora of other errors you're likely to find, you won't find anyone using a shortwave operator's Morse code shorthand for "good."

http://www.newegg.com/Product/ComboDealDetails.aspx?Ite... Phenom II 720 with the BioStar 790GX $185 after MIR
http://www.newegg.com/Product/Product.aspx?Item=N82E168... 2x2GB Corsair DDR2 800 $20 after MIR

$205 after MIR

The 3300 is a great videocard for last gen FPS like FEAR and HL2 and Quake 4. They will all run fine at 1024x768.

You can save $35 by going with an AMD Phenom 9600 but its not that great for single thread apps but is great for multithreaded apps.

If you add a 4830, you'll have a very capable machine that should be able to play Crysis at high at 1280x1024.
