Dear Paul Henningsen, may I suggest a charting scheme.Keeep one variable(price) instead of two(cpu +gpu). Charts can be made out for every cpu+gpu price on one axis and fps on other.say on x axis we have all the price points marked as no 1,2 3 but to scale, on the y axis we have fps.Charts be made separately for all resolutions tested.sure the combination will have many points but it can also be split into more graphs of different price range if need be.The no. used in x axis will identify its price and cpu+gpu combination used. Thus even if price change it will only need shifting the price point nos. viz. 1,2,3 on x axis.for costlier combination achieving lesser fps the points can be greyed. Seven games will need 7 lines on this chart(though can be closely spaced ones),plus add in a reference line at 40 fps.And finally we can have (average fps of all games)/price histogram for all price points.thus for each resolution we have two charts(normal+histogram). It will be very easy to suggest a combination for a given resolution which will also be easy for viewers to see. Hope this finds favour.
Thanks
