Hey Fellow Gamers. I'm about to purchase a new graphics card. I'm torn between the GTX 460 and the GTX 550 Ti AMP Edition. The latter is Overclocked. I currently have a Geforce 9800 GT akimbo (1GB) that has worked great for me for three years now. There is nothing wrong with my current card. I just want DDR5 memory. The 550 Ti AMP edition is overclocked. I will be going SLI when I do my new build. But for now I would be satisfied with 1GB. I have also been peeking at some ATI Radeon cards. The 450 does have a lifetime warranty. Please advise. Thanx.
