And yes a lot game at 1920x1200 EXACTLY where the 4870 shines against the GTX260. When you put 8xAA and 16xAF on the 4870 beats the 260 EASILY almost in all games.
And newegg keeps changing prices faster than you can keep up; so do not quote me on newegg whent hey change a few times. So when I looked it up they were even. As of right now at 9:46 AM EST the cheapest 260 is $265 AFTER rebate and shows it plain as day. AND $255 for 2 brands of the 4870 - so you go learn how to use Newegg, lol
So even though the 4870 IS cheaper for sake of argument let's just pretend and say the 260 is cheaper at this moment by $20 or $30; still a no-brainer. Nice GDDR5 AND 10.1 support for the 4870 which in another thread titles such as Half-Life 4 and others are coming out with DX10.1. DOH - the 260 cannot support 10.1 go figure.
1) Oh for the proof you ask - from Anandtech article oh and this is compared to the 280; NOT even the 260 is mentioned because the 4870 compares so good to the 280, lol: "In fact, the few tests we did with 8xAA paints the 4870 in a much better light relative to the GTX 280."
2) Firingsquad Review: ATI?s really dialed in their 8xMSAA performance also. Whereas GeForce GTX and 9800 boards see a significant performance hit at 8xAA, the Radeon 4800 boards continue to scale well. 8xAA is actually playable in games like Oblivion, Company of Heroes, and Quake Wars. In fact, in our testing the Radeon 4850 was capable of giving the GeForce GTX 260 a run for its money in Oblivion, Quake Wars, and Episode 2, while the 4870 actually outgunned the GTX 280!
*** Oh yeah my bad again the 4850 gives the 260 a run for it's money, lol And the 4870 outguns the 280 in some cases -- sorry if I took this off topic and had to compare 4850 vs. the 260, hehe
Can find a lot more if I want to copy and paste all day, lol
