Well i was looking at spending around $300, so you guys rekon a 4890 would be better than the Golden Sample 4870? Also if i do get a monitor, i won't be using resolutions above 1680x1050
At that resolution the GTX 260 or 4870 would be enough. The GTX 275 or 4890 would give you a little extra horsepower so that you would have a little more time before a game was released that would make them struggle. As for your question above, my choice would still be the 4890.
if the 4870 and the 4890 are the same price, then there's only one choice you can make and that's to go for the 4890, it not only runs cooler it overclocks like mad, wouldn't swap mine for the world
