Question: Can I install this card on an older ASUS P5LP-LE motherboard? Specs say it can take a PCI Express X16 graphics card. Thanks!
Document: I have to say that this is deffinately the best GT640 for the money. It placed my Windows score at 7.1, and I know it's old, but I can now max out ALL of the settings in Mass Effect 2, without the slightest bit of lag or jittering. All in all I love this card. And I'm an ASUS  and Nvidia fan, so it's a win win for me.
The ASUS GT640 turned out to be an excellent GPU for a budget gamer (such as myself). I have not experienced any issues or setbacks so far, however I have only been using this GPU for a month so I might have more to say later.
If I could buy this product again, I would probably go for the (faster) 1 gb DDR5 version of the 640 gt or 650 gt card with the same awesome fan and over-clocking software from ASUS.Conclusion: Easy to install and use, awesome quiet fan, excellent overclocking software, (physically) HUGE CARDThis is an excellent card for anyone looking to upgrade a stock system, run (many) multiple monitors, or do some mid-level gaming.Great Value for your money.
I am very satisfied with this card. Used it to upgrade from Nvidia 8300 onboard graphics. This card allows me to play all my games on the highest settings. Please note that the most recent game that I own is Rage, which was released in october 2011. Installation was simple. Just plug it in and reboot. Then wait for windows to download and install correct drivers.
I have the graphics card mega overclocked and it can run borderlands 2 max graphics with just a hence of lag, I stress very very little lag. For the card being so overclocked and treated the way i treat it right now, it still isn't very loud. It also doesn't run very hot, I can not describe how truly amazing the graphics card is for the price. I have nothing negative to say about it.
I have to say going from onboard video to this graphics card AMAZING i love how fast it is. im able to run WoW on ultra graphics and alot of new games aswell like nether insurgency and some graphic instense games if you dont want to spend alot i would recommend this graphics card specifically because for how much it costs it is definitely worth it.
I'm sort of a high-end office and graphics programs user, not a gamer. The video card in my old ASUS P5WD2-E Premium, an ATI Radeon X1900 GT was bothering me because its fan was overspeeding more and more, making me feel as though it was about to fail and interrupting my train of thought. So, for $99 I jumped on this one, far superior to the other in memory size, speed, picture sharpness and cost, with no external power required.
Fast with games and easy to install. Overclocking tool is amazing. Tested with Starcraft 2, Homefront, and PayDay 2 on highest graphics
I have tested my computer. The result was that without installing driver,my operation system have worked very well with this vga card. Myreviews about that card is good without fault. Thanks for asus!
I overcame that limitation by switching cards around, but if you have a crowded PCI-e buss, it could be a problem.
Answer: You should have three PCI slots, plus one PCI Express x16 slot on your MB. Assuming there are no other cards occupying the slot then, "yes", you can install this graphics card on your MB. Also, assure your power supply output is sufficient to power this card.
