I have an Asus P5KC E3155 motherboard with quad processor, but didn't know at the time of my purchase a few years back that though advertised as having an 8 gig RAM capacity it can only actually take up to 4 gigs of DDR3 though there are enough slots to handle up to 8 gigs of DDR2.

I use this desktop for work running several large Adobe products at the same time, Illustrator, Photoshop, Audio & Video editing software, but I'm now also wanting to get into some gaming in my leisure time and want to upgrade without it costing me an arm and a leg.

I need to upgrade my video card and would like some recommendations, but I would think that upgrading from 4 to 8 gigs of RAM might help as well since I'm running all those programs (if for nothing other than to have room to grow for the future).
The second factor is that I have the option to purchase 8 gigs of DDR2 and stick with my current motherboard and processor or upgrade my motherboard to something that can handle more than the 4 gigs of DDR3 RAM I have currently.

My budget for components (other than the graphics card) is $400 what would you recommend will give me the most bang for my buck using as many of my current components as possible but having to at least upgrade to a better graphics card than the cheapo that came with the system.

DDR2, being outdated, is becoming expensive and hard to find. Still, if you can add a couple more 2GB sticks for $150 and put the rest of the money towards a high-end 'gaming' capable graphics card, that would be the most economical way to go. With the quad core, 8GB DDR2 800MHZ, and a high-end card, you should be in great shape for your productivity apps, and the latest games using all the eye candy.

Unfortunately, the my motherboard only has PCIe x 16 not 2.0 or 2.1 x 16
I haven't been able to find a decent gaming graphics card for PCIe x16 on Newegg.com or Microcenter.com

I'm thinking that I'm going to have to upgrade my motherboard and cpu, but perhaps I can just buy 4 more gigs of DDR3 133 since I already have 4 gigs of the same?

Unless you have any other recommendations?

Not to worry. All PCI-E x16 cards are backward compatible. Even if your board was of the original ver. 1.0 design, any modern 2.0 or 2.1 card will work fine.

That's great news! I didn't realize that. Thanks so much.
So then would you recommend sticking with the 4 gigs of DDR3 133 or going to 8 gigs of DDR2?
