GPU Upgrade

Approximate Purchase Date: e.g.: most probably this week


System Usage from Most to Least Important: gaming


Are you buying a monitor: No


Parts to Upgrade: GPU


Do you need to buy OS: / No



Location: Poland


Parts Preferences: ATI


Overclocking: Yes

SLI or Crossfire: No

Your Monitor Resolution: 1920x1080

The rig I have:

Mobo: ASRock 990FX Extreme3
CPU: AMD Phenom II X4 Quad Core 965 Black Edition 3.4GHz
PSU: Corsair CX Series 500W ATX
RAM: G.SKILL DDR3 2x4GB 1600MHz CL9 RipjawsX
GPU: Radeon HD4870

I'm upgrading the gpu simply because 4870 doesn't cut it anymore, I need something more powerful. Since there are various differences in currency and pricing, I will just say that HD 7850 1 gb is the most I can afford but I think I'd prefer something a bit cheaper. Also I'm not sure whether 500w psu is enough for it? I dislike nvidia so I would really appreciate some radeon suggestion.

Thank you very much for your help!
Kind regards

Hi. If you can afford the HD 7850 1GB, go for it especially at 1080p. Or else the next choice for you would be the HD 7770. Your CX500 PSU is more than enough for either graphics card and more.

I agree, that card will make a big difference in your performance.

too much?
Sapphire HD7850 2GB Cena brutto: 745,- złCena netto: 605,69 zł

there is also this:
Gigabyte GTX650Ti 2048MB Cena brutto: 625,- złCena netto: 508,13 zł

between a 7770 and 7850 for performance.

and finally:

ASUS Radeon HD7770 2048MB Cena brutto: 589,- złCena netto: 478,86 zł

yes, i picked all 2Gb card which might be a little much for a 7770 and even the 650ti. but better to have it and not need to than to need it and not have it.


(edit: looking at the price/performance that 650ti is very attractive esp. if the 7850 is too much)

good luck.

Looking at the prices and various benchmarks I think that 7850 might be the best options after all, even if its bit expensive for me. The performance difference between 7850 and 7770 is really big for such a low difference in price. Thanks for help!

Without creating new thread, I would like to ask if this psu is enough for radeon hd7950 ?

yes, just about all 7950s will use ~175 watts at most when gaming. but in terms of overclocking both the cpu and gpu you may face some limitations; which CX 500 is it? there is one with 38 amps on the 12 volt rail and one with 34.

I'm not really good with psus but the max load on +12V is 38a according to the box I have before my eyes, so then I guess its 38 amps version?

ok, there are a few different CX500s floating around in different parts of the world; just checking.

just an FYI, a 7950 can get up to 200 watts with a crazy overclock; it would depend how high you have to set the voltage when overclocking. a 965 BE can get up to 175 watts ( +50 more than stock) which again depends on what voltage you need to keep it stable.

the 375 watts for just the gpu and cpu, not adding in the chipset, RAM and hard drive needs (~35 watts), is pushing that "max" power of 456 watts pretty close. oyu can run a 7950 "out of the box and overclock the cpu to keep it from being a bottleneck. but if you are looking to overclock that 7950 also, a 550 -650 watt PSU would be most desirable.
