So right now on Newegg these three cards are about the same price, 4870 is $75 5670 is $80 and 6570 is $80, and my question is which of these three will give me the best performance? I was leaning towards the 4870, but 512 MB seems really small (Skyrim is a big reason for my upgrade) even if it is DDR5, and the 2 GB on the 6570 is pretty sexy even if it is DDR3 on a lower end ,but newer, card. I'm mostly just looking to play new games on med settings at a good framerate without spending more than ~ $80. Also from looking at pictures on Newegg the 4870 has 2 PCIE 6 pin slots, but I don't see that anywhere on the specs? If it does need them then I'll need a new PSU, but I'll probably need a new one anyways because I think my current one is only 350W.

If you have another card suggestion I'd like to hear it, but it seems like these are the best fit for me.
Any help/advice is much appreciated! Thank you!

The HD5670 is the fastest you can get without upgrading your PSU.

I'm not really opposed to upgrading the PSU if the performance increase is significant enough. With only 512 MB would the 4870 even be much of an improvement over the 5670? Also after searching the manufacturer's site the 4870 only requires 1 x 6 pin PCIE power connector unless I double up on cards, which my MOBO doesn't even have room for lol. They do recommend a 450W PSU though so I'd still need to upgrade, it just gives me a few slightly cheaper options.

performance wise 4870 will win any day among the card you list though your psu won't be able to handle it. 4870 is a bit faster than 5770 if you compare the two based on stock vs stock. rather than 4870 it is better to go for 5770 or 6770 but i believe it will cost more and you will need to replace your psu as well. if you don't want to go over 80 for the gpu your only choice will be 5670 or 6670. personally i think that 2GB DDR3 on 6570 is useless. on low resolution you will not need that many VRAM. on high resolution the card is too weak even if it has that many VRAM available

What resolution is the monitor you are using ? I really hate those options you have. Pony up a little more cash. I agree with RENZ... you should get together a few extra bucks for the 5770.

Wont I have to upgrade my PSU for a 5770? Also I didn't think the performance increase was very significant compared to a 4870 (512 MB is still scary though) and they're almost $50 more than this particular 4870. If I'm gunna upgrade my PSU that's even more incentive to go for the cheaper option haha.

i think your biggest problem is your PSU. with 350w the best you can get is 5670 or 6670. be it 4870 or 5770/6770 you still need to get new PSU. 5770/6770 might be a bit expensive than 4870 but it use less power and comes with dx11 capabilities. i think this one is a good deal:

the price is around 90 after MIR.

hey., I am looking also and came o the concluson the 'Radeon HD 6670 is the best bang at just about $100.00. Price as a main factor, the card specs will tell ya most of what you want to speculate over versus this card or that. These use no outside power supply, but still if one games alot then at least a 600 watt power supply is best. The one i found was at 'Amazon' under computer components. The one listed is an XFX card ,which is the brand i have now...good choice me thinks. Good luck!

If you want much of a gaming card at all, you need to upgrade your PSU, a 350 watt PSU won't cut it.
Do not base your decision on memory amount or type on a particular card, it has very little to do with how the card performs. The fastest card listed anywhere on this page is the 4870, by a good amount, but your PSU will not run it. There is no reason to put more than 512 meg of memory on many cards, because they simply don't have the power to run the game if you turn detail and resolutions up high to actually use more memory. The only card you have that could actually make use of more than 512 meg is the 4870, the rest of the cards it is a marketing ploy to make the card more attractive, they are not powerful enough to make use of the extra memory unless you bought a couple of them and put them in Crossfire, but even then it would questionable whether they could really use more than 512meg.

What is your PC? If it is a prebuild like a Dell, we need to know exactly what it is, because some of the Dell PSU's are actually quite good, supply a high amount of amps on the 12 volt rails where how a PSU performs really counts, and can support a more powerful GPU than a standard no name cheap PSU. So let us know your complete build please.

For instance, if your PC is a Dell, it can run a 5770.

It's a Gateway GT 5620 (full system specs here http://reviews.cnet.com/desktops/gateway-gt5620-pentium... ) but I'm going to be overhauling it big time with this upgrade. Aside from the graphics card I'm going to be upgrading to a 3.1 GHz triple core CPU (probably) and a new MOBO with a PCIE 2.0 slot and DDR3 support. I was hoping to keep the PSU, but they're pretty cheap so it wouldn't hurt too much to upgrade.

Apparently I read wrong when I opened the thing up the other night, the internet says it's only a 300 GHz PSU.

Edit - "300W" lol dumb typo

This is 2011. Not 2001. That year i was using a 350watt psu, and a first year P4 CPU. What kiind of computer uses only a 300 watt PSU? I think even something like a 'Corsair 400 watt PSU would suffice but barely.

If possible, and i know mney is tight these days, pick up a good name brand 500 watt at bare minimum or if it's possible, take the rig back and upgrade to something with a bigger wattage PSU. :bounce:  :hello:

The HD4870 is nearly twice as powerful as the other two cards. As the others have said though you will need to replace the PSU to run it. Do NOT get a random cheap power supply. The PSU is the last component where you want to skimp on quality and there are tons of terrible ones out there.
This is a very good deal on a good PSU(you need to buy it today to get that price);
