Hello everbody! I have the opportunity to buy some cheap Hardware in a Swiss auction website. - I was wondering if it's a good idea to sell my Zotac 9800 GT OC (Performs on the level of a 8800GTS G92) for a HD 4830/4850. If I get a HD4830 for instance, and OC to boost it, then acquire another cheap one in like 4-5 month with a bigger PSU. Worth the hassle? Or is a HD4850 a decent upgrade from a 9800GT OC? - Is going RAID worth the hassle? I could get another HD322HJ from Samsung. Will I notice a significant boost in system reponse and or Boot times? Worth the risk of loosing Data in case of failure? Thanks for your help!
