So you game on dual monitors? Or just the single 1680x1050 monitor and the other for Facebook? If so we still need to know how many amps are on your 12v rail. Don't say it's a Cooler Master or any other name, give us the amps on the 12v. What specific Phenom processor is that? Please clarify some of these things. I assume it's the Phenom II x4 965 and some PSU with around 500w power. You should be upgrading to ATLEAST a 7770 if you want to have a noticeable and good increase of performance.
As far as bandwith goes is should be backwards compatible and the performance loss should be around 5%. As for a graphics card we still need to know how many amps are on your 12v. I highly recommend a 7770 and if you can find a GTX 650Ti for $130 US or less, go for it.
What about buying online? I am not from the Philippines (in fact I'm Canadian), nor do I know any good websites to buy computer parts from. If someone else does and I'm sure someone will, please post some websites from buying there. I have tried to find some websites but they didn't seem legit.
Ok , something i forgot is to thank all of you for you answers and guidance...and my goodness , very fast , it almost like chatting.
Now , my PSU is Leadway PA4-550w
And the outs are:
3.3 , 14amps
-5 , 0.5 amps
The video card should have multiple outputs. It would be VERY unusual if it didn't. Just connect each monitor to a different output, doesn't really matter which, then adjust the settings to you usage in the card's control panel.
Continuing my investigation , i tried to overclock my 9800GT and check my FPS with a reference position in X-plane, the normal values are GPU 550mhz , Mem 900 Mhz and Shader 1375Mhz,i went until 640 , 1100,1375 , without any changes in the FPS so i tried to underclock , and no changes until i reached 400,600,1375,then from 28fps it goes down to 25 fps.
Does it means that my Grafic card is not the bottle neck of my system?phenom ii x4 945 deneb
