I reckon it's still a good 2 years before I'm even considering a graphics card upgrade.
Still considering a 1TB SSD, prices are almost reasonable now.
EDIT: Next on my list is a new headset though, as my replacement G35 has developed a hairline crack on the right cup holder casing (kinda difficult to explain with words). Reinforced it with a liberal application of Sellotape for now but that plastic goes pretty quick once it gets damaged and then the cup won't stay straight.
Currently looking at the G933 as a replacement, especially given the device switching support, but we'll see.
