I'm looking to upgrade my 4870 with a gtx 770. I would like to not upgrade any other components until I build a new pc. At that time I'll get another 770 and sli. Current system specs...

-Phenom II x4 @3.2
- Mobo http://www.asus.com/Motherboards/M4A785M/#specification...
-Ati 4870
-6 gigs ddr2 ram
-550 watt psu, http://www.amazon.com/BFG-Tech-BFGR550WGSPSU-550-Watt-S...
-1920x1200 monitor

A couple concerns of mine are,

- will there be any major bottlenecks that will make the upgrade not worth it?

-550 watt is the minimum for a 770, will it be ok?

Thanks for taking a look , and advice would be appreciated.

(if links to parts are needed let me know and ill try and find them, although I'm not sure if the internet goes back that far!)

Hi. With DDR2 Ram, that is an older system. I don't what PSU you have so it may or may not be enough. Another thing to take into consideration is the PCIe Bus. Don't know what motherboard you have, but the would be bottlenecking of the Video card by the PCIe bus. If it is 1.0, then it will be serious; 2.0 it will be noticible with the 3.0 Card.

Thanks for the quick response, I'll update my post with mobo/psu links.

Actually the 4870 uses almost the same about of power as a 770 (assuming no OC). Though the question is do you plan on building a new PC in the future and use your old Video card or are we talking building a new PC in 2yr from scratch and keeping the old PC as long as possible.

If you plan on keeping the old PC an building a new one in a year you may want to look in picking up a cheaper video card to get you by like a 650 TI boost or a 7850 both cards are better than your current card will match well to your CPU and use much less power than your 4870.

So basically nice upgrade for $150 and you can save the $250 towards a new PC.

If the mobo and psu can cut it, I'd love to get the 770, any other thoughts/advice?

I plan to build a new pc in less than a year, when I do, I would pull the 770 out of my old pc, get another, and sli. The money spent now would just go into my new build. The 770 ,if my current pc can handle it is what I'd like to go with. If i were to build a new rig today I'd go with 770's in sli anyways.
