look into a Core2Quad for that slot. It will speed things up immensely

i was lookin same catagory but whitch one and do i have to get new psu

 

[ScrewySqrl]

I'd get a new PSU, just because you have a no-name brand.

I'd say, if you can swing the price one of the 9xxx Core2Quads. should see you through for another year

my friend who i helped to buil a system has 500w psu and 2.8ghz C2Q 9xxx and 5770 sappihire gpu, he has done fine whit it
but my psu says max peak:550 and max combined 140w+348w=488w WTF!??!

 

[ScrewySqrl]

what matters is the 12v amperage.

 

[vault dveller]

+12v1=20a and -12v=0.8
i took these from my psu side

 

[ScrewySqrl]

yeah. That PSU is crap. Its undervoltage, has weak 12v amperage.

buy a new psu: Antec, Corsair, Sea Sonic, XFX are good.

That's right. More than the supposed wattage, what really matters is the total amperage on the +12Volt rail(s). A decent quality 500 watt 80+ unit is gonna have close to 40 Amps combined on it's +12V rail(s). [Volt X Ampere = Watt. Hopefully you guys were attentive during your Physics Classes So 12V X 40A = 480 Watts]. Some manufacturers use dual rails while others go with one.

Coming to your original question, your CPU and GPU choices will really depend on which games you wanna play and at what settings, on what resolution. If you intend to stick to the 9800, get an E5700. Should be more than enough. OC it if you have to. Just make sure you upgrade to the right BIOS version.

Here's a list of the supported CPU's - ASUS P5KC processor support

f--k money is now in thight... well lets face it how big psu should i get?
and is there any chance to get by whit old psu?
and look at the irony below... oc psu... right

 

[ScrewySqrl]

something around the listed voltage for your current shoudl do. 450-550W fom a reliable brand.

I personally like the Sea Sonic S12II 520W model. 34A on the 12V rail, its $59.99 US.

sorry mistake there was two +12v 20a so its a dual rail
is it good psu

 

[calguyhunk]

Never heard of Altis, but 2x 20amp +12V rails doesn't sound bad for a 550 Watt unit. An 80+ rated one would have had a bit more. Try to find out the rated 'continuous power' output. But really, if it's doing alright, I don't think you need to worry 'bout it too much.
