Summary: I am not a gamer, and don't need a screaming fast card. I just wanted one that would support two dual link monitors. It works very well for that. I did have to disable the on-motherboard Intel graphics to get all four monitors working (an HDMI and a 30" 2560 x 1600 on an EVGA 610, and a two 27" 2560 x 1440 on this Zotac). I love my square meter of monitors, though all my co-workers laugh at me.
Summary: This is the perfect GPU for you if you don't want to upgrade your tower's power supply. I recently bought a new computer (an intel i5-3330 with 8GB RAM and 1TB HD) with onboard Intel 2500 Graphics. I am not a heavy gamer, but I do play a few, and while my computer is more than powerful enough for most applications, it's 3D rendering scores were weak. I figured that an upgrade of the GPU would also require an upgrade of power supply as well (mine's 300W).
Summary: You get your money's worth with the Zotac GeForce GT630. It is a card that performs to standards better than cards 2 years older than it, and is competitive with prices for other off-brand-name products. The issues come into play when you go to update the drivers. I used the drivers on the CD to install the card initially, then went to the website to update the drivers to the latest update, but had to hard-restart my computer several times while installing the drivers,...
Summary: this card is a huge and overpriced gimmick. they took a regular GT 630 added another GB om memory and DECREASED the clock and memory speeds almost by half. the speed is now about 810 MHz, so it can only address about 750 MB of the memory. dont waste your money like i did. this can play starcraft 2 on 1024x768 at all details low, or turned off at about 15 fps. my 7 year old laptop can play skyrim on high with about 40 fps. this card wont play skyrim at all.
