Bit out of touch since moving on with what's current. The time has come to replace my ageing Dell XPS laptop. Looking for something better. I need high performance (not necessarily gaming but very fast for general use) at least 17" high resolution screen (not HD limited). I guess at least i7 processor, memory can be expanded and drives expandable. Sata 6Gb. Budget between 1-2G So can any knowledgable person(s) offer suitable suggestions?
