I have a Gateway dx4850 27eu , with a i5 2300 . I be a noob when it come to upgrade and Gateway really do not offer much help . I add a gt 430 card to it and the fp in swtor with the setting on low stunk ; it be playable but wonky enough it bother I . due to the limited 300w power supply in the dx4850 , I be go to have to do some upgrade before I could even think about get a decent graphic card . I start with the power supply : Corsair Enthusiast Series 750-Watt 80 plus bronze certified power supply compatible with Intel Core i3 , i5 , i7 and AMD platform - cmpsu-750txv2 I probably could have go with a 650w or maybe even a 550 but it be only a few dollar more for the 750 . this power supply be about a inch longer than the stock 300w power supply in the dx4850 ; it be snug but there be plenty of room around the fan . it work great ! next be the graphic card : EVGA GeForce GTX560 Ti 448 Cores FTW 1280 MB GDDR5 , Dual-DualLink DVI , HDMI , DisplayPort , SLI Graphics Cards 012-p3-2066-kr I have plenty of power for a card but space be a issue in the dx4850 . this card be around 9 '' long and fit perfect - any longer and I would have have to buy longer power cable to make room for exist short power cable in the case . I get those sweet upgrade in and then notice that the case be get hot , really hot . so , I need fan : Antec pro 92mm double Ball Bearing Case fan with 3-pin and 4-pin connector I get this fan for the case , it connect with the 3 pin -lrb- there be only one wire connect to the 3 pin connector -rrb- to the mother board and a 4 pin to the power supply . it be much more powerful than the dx4850 stock fan and work great , the screw be kinda tough to get in but I highly recommend it . since my case be so hot and the fan be pretty inexpensive I also add this fan : Antec Cyclone Blower Case Fan for any expansion slot this fan be also easy to install , it be powerful and help vent the graphic card great . the air blow out the back , great little fan . all this be cheaper than buy a new computer with the same spec and the end result be great . I go from barely run Star Wars The Old Republic on low setting to where I can run it smoothly on high setting . the heat make I a little nervous , this be a Gateway and all , so I run swtor on medium setting and it be awesome !
