AMD 6670 vs 6570 vs GMA 3100 for low-end gaming

the 6670 and the 6570 performs pretty much the same and both are hundreds of times better than the GMA 3100.

Pick the 6670 with DDR5 memory. The 280W PSU is too low for a 6670. Get at least a 400W PSU from a decent brand (Corsair, Seasonic, Enermax...or maybe even XFX and Antec). Make sure the PSU has at least one 6 pin PCIE connector.

Some examples:

XFX 450W Core Edition PSU: http://xfxforce.com/en-gb/Products/Power-Supply/XFX/Pro...

Thanks for your replies so far.

I just realized that the most requiring game I'm going to have a go at only requires a 5450, and I'm pretty cheap when it comes to gaming..

I could still really use some info on the PSU though; is 280W enough?

280 is enough, if you read through this

you can see a lot of people run 6670s with 250ish power supplies. The 6570 uses a bit less power.

the 6570 should be worth the money over a 5450 or a 6450. The 6450 is 2x the performance of the 5450 and the 6570 is about 3x faster than the 6450.

The Radeon HD 6570 (OEM) 1GB makes use of a 40 nm design. ATi has set the core speed at 650 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.
Compare all that to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. ATi has set the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this card. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.
That Mean A 6670 is A perfect Buy And also a 3100 is a crap card

Thanks for the replies.

Considering my needs though, I'm going with the 6450 and I will probably spend the extra bucks on a RAM upgrade.

I'd really suggest you go with something more powerful than the 6450.

There is a fine line between budget and waste.

If you're wanting to do anything other than browse the internet, it's rarely a good idea to go with bare minimum. Your CPU certainly isn't a game changer, but it's a decent CPU. The PSU really is too low, but if you feel like rolling the dice it might do.

How much RAM do you have? What type?

Basically my recommendation (though the RAM question is important) would be the 6670 and a new PSU. Anything less than that and you should just keep avoiding gaming.

I will, that's part of what I'm aiming for here.

The RAM is 2GB, DDR2 I think. I can't tell until I have the thing with me though, but it's an office computer from 2008. I plan on upgrading to 4GB, probably with a new PSU in the deal.

If it can run the Source engine, maybe apart from the latest release, on an enjoyable level, along with being able to run VHE 4.1 and something like Blender for making models at a similar level, then that's all I need. Frankly, I don't mind not having the option to play the newest games.

But when you say I should avoid gaming if I stick with this decision, what games are you talking about?

HD 6670 DDR5 memory, overclock it by 10%, and it takes power from the motherboard, not the PSU that requires a 6-Pin connection. It can also BF3 on High with Skyrim maxed out but I also have a i5 3570K as well. =)

Thanks for the input, but you didn't read the thread, did you?

In that case I would recommend the 6670. It's not the bare minimum to accomplish what you need, but it is right in the sweet spot. CS isn't too taxing, but games like Portal 2 (especially when you get into the fluids) can be a bit more so, and the 6670 should be able to handle it much better than the 64xx. You've got a plan for RAM and PSU, so I'd say you're set after that.

With regard to my comment about avoiding gaming, anything less than say ... the 6570 you mentioned, and it just isn't worth the money because you're not going to be able to play the games or get the level of enjoyment out of them to make it worth the money. Bare minimum tends to lead to frustration. It lets you experience it, but it's not a very good experience. Usually a step or two up will greatly improve the overall experience and leave you much happier with your decision.

You got me convinced.

I watched gameplay of Portal 2 from the 6570 and the 6450 and although both were able to run the game, the framerates were just too low on the 6450. I'm surprised I didn't notice this before.

I'm going with the 6570, meaning that I will have to pay a little more than I had hoped for, but anything less would just be a waste.

Thanks for the help!
