Newest high end games on max = most expensive hardware. Figure out how much you can spend and buy the best you can.

Well, Crossfire only makes sense if you can only cough up 150 bucks now, and intend to buy another one in the future. Still, by the time you buy the second GPU, it won't be a good setup.

For 150 bucks, you might find a 6870. It will run today's games well at 6870, possibly at highest settings. Antialiasing might hurt your performance a lot. For Battlefield 3, average FPS should be 60 at high settings, 30-40 with 4xMSAA and post processing.

I have to say I'm against crossfire at that price point. I had a pair of 6870's, which were great, but had a lot of issues with new games and high quality settings. Stay away from dual-VGA setups if you can.

If you want to run demanding games, as you seem to, and at high/ultra settings, the best thing would be to save up until you can afford something like a GTX 670.
 


You are not going to be able to find a card that can run those games on medium for $100. $150 will get you a card that will run them on medium, barely.

Thank you all for your response I did post that what mother board I have and thats its pci 2.0 and has crossfire x (RADEON only for the ones that dont know ) and Im wanting to run two cards please just the ones than know post


 


Well my friend, it's not that we don't know, it's just that it makes no sense corssfiring entry-level cards. You will have crap performance, bad power efficiency, high noise and driver issues. If you actually want to intentionally screw yourself for the sake of Crossfire, do what I suggested and buy a 6870, than a second one when you can afford it. If you must buy the two cards for 150 right now, which is even more stupid (sorry for the lack of a better word to describe it, there isn't one), try 2x Radeon 6670. You should max pinball 3D at least.

You do realize that just because your motherboard supports Crossfire doesn't mean you have to use it, right? You said you want to play things on ultra, and you want to use two cards. Well, there is nothing wrong in wanting, but you just can't have it for 150 bucks.

Im running a msi radeon hd2600xt 256m core clock is 850 Ive been running star craft 2 on ultra 1280x960 now it will only run it on high at lower res.


you said to get GTX 670 this is a geforce so your saying that geforce works best on crossfire x right ?

the people at tigerdirect said that running two of these cards HIS H545H1GD1 Radeon HD 5450 Video Card - 1024MB DDR3, PCI-Express 2.0 (x1), DVI, HDMI, VGAItem#: H231-5462 | Model#: H545H1GD1 would be like running one of these Visiontek 900338 Radeon HD 6870 Video Card - 1024MB, GDDR5, PCIe, Dual mini-Display Port, HDMI, Dual DVIItem#: V261-6870 | Model#: 900338 I dont think thats true what do you think ?
 


The GeForce GTX 670 would use SLI rather than Crossfire. Different manufacturer, similar technology, same idea. Crossfiring two 5450s wouldn't be anywhere near what a 6870 would be capable of doing. I'm not even sure if the 5450 can be put into Crossfire. The 6870 is a very decent card and would be a good investment
 


I'm saying a GTX 670 works better THAN crossfire X, not ON crossfire X. I mean ONE GTX 670 will beat ANY TWO radeons you can buy for 150 bucks any day.

Let's get something clear, crossfire is not an interface, its an optional, additional technology. Any video cards you attach to your motherboard will have to be PCI-E, meaning they will communicate through the PCI Express interface. That can be either a Geforce or a Radeon, regardless of the motherboard supporting Crossfire or SLI. If you want to use two video cards for additional performance, you will need a motherboard that supports either Crossfire or SLI. If it supports SLI, you can use two Nvidia cards. If it supports Crossfire, like yours do, you can use two AMD/ATI cards. Either way, you need two cards of the same model (there was a time ATI supported different models of the same generation, but that never worked well).

What I'm telling you is that, for crossfire to make sense, the combined performance of the two cards need to be considerably higher than that of a single card of equivalent price. If you were to buy a second HD 2600, your performance would still be way lower than a single HD 6870. A GTX 670 will be even more impressive. So, if you can save up and buy a single, powerful card, like the GTX 670, you will end up having a much faster setup.

As for the question about the 5450: A single 6870 is will be worlds faster than 2x5450. Check these links if you want to confirm:

Arkham asylum 1680x1050:
HD 6870 = 134 FPS
2x 5450 = 31 FPS

In fewer words, forget crossfire and buy the best card you can afford, Radeon or Geforce.
