Hello, I have DKA790GX Platinum motherboard, a Phenom x4, and an old 3870 GPU. I'm upgrading and don't have a ton of money to spend. I'm currently looking a gtx550, but am unsure that it will run with my mobo and CPU. I'm looking at just upgrading the graphics card, but if I have to upgrade the mobo then I guess I will. Also I would like to be able to play BF3 on high and 60 frames.
Don't run a dual card setup to start. Sometimes you run into issues with micro stutter and it isn't worth the extra trouble. General rule of thumb is to start with the best single one you can get and add in a second down the road (which luckily your motherboard can support) if you find it isn't adequate anymore. If you start with two then you don't have any upgrade options just replace the entire setup.
That's only the processor he can overclock the GPU though. His motherboard is fine for that and won't have any problems. It's mainly the PSU that is a question for handling the OC, along with a smaller extent the CPU since it is taxed more with higher settings.
Edit- actually you can overclock the CPU too, if it's unlocked that is. http://www.overclockersclub.com/reviews/dka790gx/
One of the main things in conclusion is how they didn't have to add extra cooling for the motherboard, it kept cool itself.
Costs more money starting price for the 560Ti. The difference is minimal after the extra shipping charge. Lastly the 6950 is actually a bit more powerful than the 560Ti. http://www.tomshardware.com/reviews/build-gaming-pc-ove...
I quote from the first page of this article (right under the parts they picked and their prices).
"When we made our purchase, there were only two worthy GPU upgrades within reach: Nvidia’s GeForce GTX 560 Ti starting at $210 and AMD’s Radeon HD 6950 1 GB at $240. Naturally, we set our sights on the more powerful board"
Alright that should be fine.How old is it though? 5 years?
Yeah honestly your not going to get the most out of your upgrade with your current system.It's just far to old for a high end game like BF3.I think the best thing to do is to just save up a bunch of money and rebuild from scratch when you have the money.I'm sure by then prices will have dropped for the new series of cards that just released.
