gpu upgrade

Apr 15, 2017

I have gtx 660 2gb ram, 2tb hdd alienware x51. I want to upgrade the gpu. I have been told that the highest I could go was the gtx670.

I really need some good advice on what gpu I could actually replace it with please.

Thanks in advance,

It would help to list what power adapter in watts your using and what generation of x51 your is. There are 180, 240 or 330watt power bricks, and for example mine is a x51 r2 (second generation) with a 240 watt power brick.
I recently upgraded to this video card the card fits runs fairly quiet, double the ram of your old card, doesn't even require external power.
here's a compare between a GTX 660 and GTX 1050TI 660-vs-Nvidia GeForce GTX 1050 Ti MSI OC 4GB

RX 470 (9.5 inches) blower type recommended works great, and if you in the market for a new monitor Freesync monitors are no cost added unlike gsync .

unfortunately there mostly sold out except dealers that jacked prices was 174 US a bit ago

I just installed an EVGA 560TI 1GB card in my X51 R2 with a 330W PSU playing PUBG and it was running for hours full speed and didn't flinch. The EVGA 560TI is a 210W TDP card so it should have no problem running the GTX 10 series cards... unless you got a bum PSU.

I strictly recommend running blower style coolers though, the EVGA got quite hot because its fan over open heat sinks, anyhow it still worked with no problems. Hope this helps.

Well, actually the information I just posted above might be incorrect. I checked another source and the EVGA 560ti is said to have a TDP of 170W, not 210W. Also, my X51 has the 330W PSU, i7 4790, 8gb RAM, Samsung SSD, and a noctua 80mm exhaust fan mod and it will not boot with a GTX1080 installed. So, if it works with the 170W GPU I will be forced to add a higher Watt PSU or downgrade to the GTX1070.

I think I'm going to mod the **** out of it.
