Hello and thank you for taking the time to read this. Lets jump right in. I have an HP pavillion slimline s7713w running windows 7 x86 with 2GB ram and an athlon X2 4200+ 2.2 ghz cpu. The motherboard is an ASUS A8N-BR Pyrite-GL8E..... There is only 1 PCI slot open. I would just like to maybe get a better graphics card for it to make streaming youtube better (my daughters computer) i dont need anything super fantastic, just something that will help make streaming better. if you can list names and models that would be great. I know it needs a LOW-PRO but thats where my knowledge ends. and yes i have heard maybe buy a new computer.... wont need to if i can boost just a little extra out of this thing!! thank you for your time!!!
