i picked up my 8800 gtx today but i have a problem. i have a dell dimension e520, i have a 600 watt ocz psu and a pci-e x16 slot. the problem is that the heatsink ( the black thing ) comes in the way of the card(the heatsink). so its not fitting. is there anything i could do ? i heard this model uses a btx motherboard and i would need a bigger case but i doubt that would help since its the motherboard that matters. any solutions or would i need to build a new rig ?
