apart from the slight core clock speed I see no difference can someone enlighten me because the lighting is £400 ish and the gaming is under £300 atm I'm upgrading from the asus Radeon HD6950 (don't think changing the bios to 6970 is good enough now) I have everything I need to run it etc, 900w psu saber tooth P67 and i7 2600k (yes I'm going to upgrade motherboard and cpu next).
Also if the Lightning is the better option can I run it at the 900w setting?
