Pavilion tower GC670AA-ABA a612n
Windows Vista Home Premium service pack 2
2.00 GHZ Intel Core 2 Duo
3.0 GB RAM
Replacing NVIDEA GeForce 8800 GT
I believe I replaced power supply with 450 watt.
I could upgrade to a AMD Radeon R7 240 but I would prefer to choose a Radeon HD 7770.
I understand I need a second connector to the power supply? I will need the space for this larger card but not sure.
I need a DirectX 11 compatable card
Thank you,
