Upgrading to a better graphics card

Lolzdecap · Oct 20, 2014

I already have one GTX 460 in my build and I am hungry for more. I have found many GTX 460s on ebay under $50 (Which happens to be my budget). Do you guys have any better Ideas or tips?

I have capable motherboard and I have a 550W power supply which I have calculated to be enough for my system and 2 graphics cards.

You guys are awesome thanks.

Two questions. First, and most important, what is the brand and model number of your PSU. Second, what is you motherboard model number and do you know if it even supports an SLI configuration?

GTX 460 is a 160W TDP card and a 550W PSU will not suffice for SLI, no matter how high quality it is. I'd suggest to wait and fund yourself to grab a GTX 750 Ti for $100, much better performance.

Well, that's a tier 3 PSU, not great by any means, but not terrible either. There is a note on the Tier list saying technically this is only a 500w PSU, so that's just something to also keep in mind. As mentioned above by meteorsraining, that wouldn't be enough by any stretch of the imagination to power two cards in SLI so as he also mentioned it would be better to find a single card solution that you can use with the PSU you currently have.

If you can afford a PSU with sufficient juice (Preferably a Tier 2B or higher unit here: http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html) you could use two of those in SLI but it would barely perform better than the single 750 TI and only in games optimized for it. It would also produce a lot more heat in addition to drawing significantly more power. Better to find a single card that will do what you want.
