2 GTX 460's (768 mb) in SLI them will be the best option! Of course, keep in mind that they will suck a bit of power, so you'll need a PSU hefty enough to handle them. You'll also need a mobo which will support SLi. If you can opt for two 460's, it'll cost you about 50-60 bucks more, but well gonna be worth it!!
thanks man!........ .... i'll consider that.... what about the ati radeon hd 5000 series .... i read that they produce less heat and noise and also less power consumption ..... like 5870 or two 5770 ...any idea?
The HD5870 isn't a very good card for the money imo. If you overclock it is only marginally better than the much cheaper HD5850(same applies to the GTX 480 vs GTX 470.) If heat/power/noise are a large concern for you then the HD5850 is a good choice although in terms of performance for the money the GTX 470 has it beat at the moment but it is very power efficient for its performance. This one would be a good choice as it has very effective and quiet cooling and allows for voltage increases of the core for the best overclocking; http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It has some poor reviews but most have to do with issues with the overclocking software that have since been cleared up.
Yeah, I've seen that before and it goes against every other review you might find basically so I wouldn't take it too seriously. Take a look at some GTX 460 reviews as they will be the most current and should usually include benchmarks with all the cards you are considering.
Something to keep in mind if you are considering a dual card set up now or in the future is that SLI tends to scale much better that crossfire.
I would probably recommend just going with the GTX 460 1gb and a new monitor. Especially if you overclock even just one card will do quite well at that resolution and when you have the money to add another you'll get amazing performance. Here is an article on two GTX 460s vs an HD5970; http://www.xbitlabs.com/articles/video/display/gf-gtx46...
An HD5970 is two underclocked HD5870s on one card if you didn't know.
probably.... i can push it to get 2x 460 GTX sli now.... or should i get a single 470GTX .... and get another one later?? ........ can some one provide the best vga cooling way? and if i'm going to the 460 GTX option ..... which brand?
btw 2x 460 GTX sli .... i would need a 650 w psu ? right
Dual 460's would be overkill at that resolution, unless you're planning to upgrade the monitor/ resolution. Your monitor resolution will be a huge deciding factor! If you want to see great performance from your SLI setup, consider pushing your resolution to 1680x****. That's where the cards will perform.
As for the PSU, 650W would be more than enough. Have a look at this:
A 650w of a good brand would be enough for SLI GTX 460s but I wouldn't put Coolermaster on the list of good brands.
As for 2 GTX 460s vs a GTX 470 and possibly another later... that is something you are really going to have to decide for yourself. Honestly if you get one GTX 470 there is a very good chance you'll decide that that is more than enough for now which will save you $150+ and you also won't have to deal with any SLI scaling or compatibility issues. On the other hand SLIed GTX 460s are just really fast and a good deal. It's up to you really.
Nameless brought it up again but I'd like to clarify. What we are discussing are high end set ups intended for high resolutions. This discussion only makes sense in context of a 1080p monitor or better. Even at 1680x1050 a GTX 470 is quite a large amount of overkill.
..... okyz...... then a a single 470 GTX would do just fine+a new monitor ....... and getting another one later would be great.....so .... considering a psu for a future sli with 2 470 ........ 650 w or should a go for more?........ and which brand should i go for.... ( evaga-msi-asus-pny-gigabyte) ? and the cooling for the whole case ..... and the vga cards.... i know i'm asking too much ... thanks
