macc4s · Dec 30, 2014

Hi everyone im wondering if someone could help me on upgrading my cpu it is a intel core i3 2120 LGA1155 and i need to know if its possible to upgrade possibly to a Intel i5-3330 or just something better than the i3 2120 as im going to be buying a r9 280 and i think its going to bottle kneck.

Here is a screenshot of info on my pc ( NOTE - i have 4gb of ram not 6gb but im going to buy another 4gb stick).

an i5-3340 will be a good choice or 3570

Will that work tho?

Andrynuim · Dec 30, 2014

Best option for a balanced match to a r8 280x would be an i5-3570, Xeon 1230v2, or a i7-3770, depending on price, and overall usage of your pc. For mainly games the i5, for productivity, blending, multi-core 2d/3d apps, and games then the Xeon or i7 has an edge.

Ok thanks alot i think im gonna need a better power supply for a 280 so i might just get a r9 270x will 500w be enough?

Andrynuim · Dec 30, 2014

yep 270x will be a lot better if you can afford it

Karadjgne · Dec 30, 2014

Recommended for 280x is 600w psu, 280 is 550, 270x is 500. However, with a quality psu you could drop that to 550/500/500 as long as you have 30/25/24 amps on the 12v rail. So if budget allowed, a r9 280 would be the best choice, better performance over a 270x, yet basically the same power requirements with a good psu.

http://gyazo.com/142b5f1e20927777bf77b635dc2b4e98 think i could get away with that for the r9 280 or is it a psu upgrade too?

Karadjgne · Jan 2, 2015

With 38a on the 12v rail, its more than good enough for a 280, however I didn't see a brand or model number, which is important. You can sit a terrible psu right next to a quality unit and look at the outputs and they could very well be the same. Having lower 3.3 and 5v is usually indicative of a newer design, older designs mostly used 30amps or more on 3.3v and 5v.

thanks alot mate for helping, i had a look around and came across this if this is better information http://gyazo.com/7491f9b62cc840adb33824daa66f7863, so you think i will be okay with this psu for now?

The Corsair CX is one of Corsair's entry series of psus. They are solidly mediocre, neither good nor bad. The CX use an older design, and sub-par secondary capacitors. However, the CXM semi modular version uses a newer design and Japanese solid caps on the secondaries, a much higher quality psu. For the money, a CX 500M is a good value. It'll be fine.
