I am debating between 2 budget gaming system builds, 4GB ram both, processor is same (phenom2 quad 840 @ 3.2):
A) motherboard: AMD 760G + SB710/ ATI Radeon 3000 onboard with generic/cheap ATX tower & 400w PSU
B) motherboard: NVIDIA GeForce 7025/nForce 630a with gaming case & gaming 400w PSU
B is about 30 more expensive than A, which could be spent on graphics card if the motherboard/case/PSU is not as important. I am looking at those cards within budget I set for system):
GeForce GT 440 1GB GDDR3
ATI Radeon 5670 1GB GDDR3
ATI Radeon 5750 (1slot) 1GB GDDR5 [or 5770 if worth it]
Sorted from cheap to expensive (UK prices), is the performance jump from GDDR3 to GDDR5 big enough? or is GDDR5 overkill for my setup?
also will ATX tower case with generic 400w PSU accommodate all these? and will one motherboard have any problem with those graphic cards?
Well first off, that processor isn't very good. It's actually a renamed Athlon x4. Second, you NEVER want to get generic PSU's. The PSU is probably the single most important part of your pc, it makes sure power gets distributed to all the parts correctly.
The electronics in a pc are very sensitive , so you want to make sure you get a good PSU that will not burn out the rest of your components. I suggest something like an Antec Earthwatts 430w green for a low power system such as this.
Can you list the full specs? I assume you are deciding on prebuilts correct?
There are many quality PSUs sold by companies other than the big ones. Cooler Master is not one of the big ones and sells quite a few crappy units.
Striker, you linked the EA-380D there. A good PSU but perhaps he needs a bit more. The Rosewill RG units are good and often a good buy...
mkx, you have listed a couple very poor motherboard choices. I suggest you check out the guide linked in my signature.
If your budget is very low you might want to look at an Athlon II X3 and an 880G motherboard.
My bad, I had the 380 already open earlier and must have swapped the links lol.
For OP, I also second the athlon x3. Remember that the GPU should cost more than your CPU for gaming, even when on a budget.
You also asked GDDR5 vs DDR3. This is video memory, not ram so please keep that in mind. I personally think that the 5770 is enough of an upgrade from the 5750 to be justified. However, let's get the rest of the build done and see if you have any extra for a better GPU.
Thanks for suggestions. Due to some circumstances my purchasing got delayed, which worked good because there seems to be more offers now with june starting, I'm going to decide something and order next 2-3 days
A is probably on a poor motherboard and not really a good gaming choice. Only get the AMD option if you can overclock it... and it's doubtful you'll get much OC out of a 760G board, but I could be wrong.
With option B, you have the ability to overclock the CPU quite a ways (Well, depending on the board), making it the better choice of the three.
