Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
With the specs i have in my sig, would it be worth upgrading from the 6800GT? Would that be enough of an upgrade to hold me over while i save up for a new system?
Depends on how much gaming you do and how well the games you play run on your system.
If your games run fine, keep your card. If you game a fair bit and they run rather slow then perhaps an upgrade would be good. But if your planning on upgrading the whole system it would almost make more sense to wait till then.
