Hello all. I'm looking for a GPU update this Christmas to replace my XFX 6870 1GB, which is unfortunately giving up the ghost and currently have a budget of £260 max. Here are my current options: SAPPHIRE VAPOR-X R9 280X 3GB GDDR5 OC Sapphire TOXIC R9 280X 3GB ASUS AMD Radeon R9 280X DirectCU II TOP OC 3GB GDDR5 I've been looking everywhere for the Asus version but can't find it in stock anywhere. I've also heard that both the Sapphire cards are very loud and power hungry. I've found a Toxic 280 for £267, a little over budget but I know it has great performance. However, I'm unsure just how loud it really is according to the reviews I've read. And just to confirm, if I bought the Toxic or Vapor X. Would it run well and safely with my OCZ ZS Series 500W Power supply? Thank you all in advance.
