Summary: I installed this card into my ageing Dell office PC. Installation was easy. There weren't any additional power cables for this card. I was able to spread my desktop across 3 monitors. The PC is predominantly used for office applications although I did test with Minecraft across all 3 monitors and was able to consistently achieve over 60fps (monitors max refresh rate) without issue. Card is quiet and cool running.
Summary: Got this for an old PC to replace a dying gfx card. Wanted something budget but could still play games on. First was a trip to Maplin & PC world & I was appalled at their 50%+ markup on frankly crap GPUs so had a look on amazon & found this for around the right price. Only had it a day but runs COD4 & Assassin's creed quite smoothly on a HD tv with very little fan noise.
Summary: It has HDMI, DVI and VGA outputs and does a reasonable job. On my workhorse system it scored 7.1 on Windows Experience on stock settings. It comes with an app called Thunder Master that runs in Windows so that the settings can be tweaked and monitored in real time. I've uploaded a screen shot of Thunder Master to the Amazon product page, showing mildly tweaked settings but the GPU running only 5 degrees C above a room ambient of 30 degrees.
Good budget upgrade, especially if you have on board graphics

Summary: I bought this to replace a Inno3D GT 430 2GB because of the CUDA cores. I use a Blu-ray ripper that is optimized for CUDA cores and I thought going from 96 to 384 cores would make a considerable difference. I tested using a 2hrs 40 minutes long DVD which took 32 minutes 19 seconds with the GT 430 and 26 minutes 54 seconds with the GT 640. So there is a difference but not as large as I was expecting.
Excerpt: Видеокарта тянет пока что все игры которые я ставил начиная с игры 2008 года заканчивая Crysis 3 и batelfild 3 на самых максимальных разрешениях. По сколько имею тв с 3д видеокарта отлично показывает 3д фильмы и игры тоже играю в 3д также поддержка FullHD. Видеокарта просто идеальна за такие деньги.
Pros: Очень хорошая видеокарта, пользуюсь полгода покупкой очень доволен.
Cons: Поменял старый блок питания ( Но я считаю что это не недостаток по сколько старый был очень слабый)
