http://http:// I have a Intel core i7-4790 CPU@3.60Ghz 3.60Ghz 16GB 64 -bit with a GEFORCE GTX 745 graphic card.I use this only for gaming what would be the best graphics card to upgrade to but would like to spend less than $200.Also I can't seem to find what kind <watts> my power supply is but would I need to upgrade this too?How can I find out the power supply the writing on it is so small i can't even read it with a magnified glass! Thank you so much in advance for your help ,i seem to have a problem replying to people in the forum to thank it just repeats my thread.
Be careful with some pre-built pc like HP using a non standard psu. I opened up one i7 for a school that had maybe a 10 pin going to the mainboard not a 24 pin.
