Would GPU Crossfire help? Kinda confused what Would work with my old HD 3800..
"Unlike older series of Radeon cards, different HD 3800 series cards can be combined in CrossFire, each with separate clock control."
"A later development to the CrossFire infrastructure include a dual GPU solution with on-board PCI-E bridge that was released in early 2008, the Radeon HD 3870 X2 and later in Radeon HD 4870 X2 graphics cards"
Would that mean i HAVE to get a 3800 or 3850 as second card?
The 5770 would be a nice improvement. The truth is though, you will not get to experience the full benefits of the card untill you upgrade your cpu. However if you want to buy just one part now, a new video card will help. If you want to spend less you could go for the 4770.
Shadow, don't bloat threads, you can edit them. I realize you're adding info as you go along, but it gets annoying
Anyway, in my opinion, would be to grab a 5770, assuming you have the PSU to handle it. Your rig is becoming outdated, and a 5770 is definitely a transferable item. You buy it now, build a new machine when you can afford it, and the GPU can go to the new one. Since you have onboard, you'll be able to get some money out of the rest as it's a working system, good for general use to someone.
