Cheap multi-purpose build

[MattV]

Hey guys, 2nd time build here. looking for a fairly cheap PC that will be up to the usual tasks, play a few games(nothing too graphics intense, play rpg/rts mainly), burn/rip DVD's, surf web and use dual monitor set up. Have peripherals and OS already.

CPU - AM3 Phenom II x3 710 or AM3 x4 620 - $122/$115
MB - Gigabyte 785GT-UD3H - $108
RAM - 2x2GB DDR3 1333 G.Skill-NT -$118
HDD - WD 1TB SATA - $105
GPU - 1GB 5750 Gigabyte - $161
PSU - Antec Earthwatts 500W - $95
Case - Antec 300 ATX - $81
DVDRW- LG SATA DVDRW - $38

Total $828/821(AUD)

Questions:
CPU, any real difference between the 4x and 3x here for most tasks? I do a bit of ripping so I'm guessing it's helpful for that but just looking for best all round performance tbh.

MB, any significant difference between 785 and 790 chipset other than ~+$50(AUD) increase in price, or should this MB be fine?

GPU, I would have liked a 4870 but seems to be a bit of a shortage in Australia and prices seem a little high (~$50 on top of 5750 price plus shipping), 260GTX is even higher than 4870. 5750 is a pretty solid card from what I've read though, correct? Guess DX11 cant hurt either.

PSU, 500W is fine for this build?

TY for any help.

That PSU will handle just about any single video card.

Looks good, you'll probably see better performance with the quad core; the triple core isn't much faster in gaming, and in multithreaded apps, it is slower than the quad core. The quad core will also be faster over time than the triple core as apps get more multithreaded and are better able to take advantage of additional cores.

Regarding the motherboard, the 785G has a slightly slower intergrated GPU then the 790 chipsets and doesn't support crossfire (at least officially); performance wise, it is about the same. Motherboard with the 770 chipset are also pretty good, and may be found for less than the 785G.

The graphics card should be fine for your setup, if you find a 512MB version of the card for less, that would be a better option as the extra 512MB doesn't give you much if any boost in performance.

Thanks for advice.

@PSU, Dropping it it down from 500W to 430W (same brand/type) should be fine then correct? Would it(430W) also be alright if I upgrade the card from 5750 to the 5770?

@GPU seems like they are only selling 1GB versions selling here unfortunately.

Regarding PSU, 430W may be able to handle the 5750 or 5770, but it's cutting it really close and you will need to have the PSU running cool. If you can try to keep the 500W, it will give you some headroom, and it will be able to provide enough power regardless of temperature (the higher the temperature, the less efficient the PSU is and therefore the less power it provides).
