Hardware price/performance guides for processors and graphics cards

What started with graphic card manufacturer's mangled naming schemes has long been continued by the CPU manufacturers. The days where you knew that a "GeForce 3" was faster than a "GeForce 2" and a Pentium 500MHz is faster than a Pentium 400MHz are gone now. CPU's clocks and number of cores can not be measured in a linear fashion, hence price comparison became very hard in the last few years. Luckily, a few tools are available to us consumers that make this a bit easier.

CPUs

First of all, there's a very neat CPU price/performance comparison list at pulsiageek's site. It's especially useful because you can sort it by price, performance or price/performance-ratio.

Graphic cards

Then there's a list of graphics cards containing cards from the old 2MB 3dfx Voodoo graphics card up to the latest GeForce GTX 295. The list over at gpureview.com does not contain a benchmark result, unfortunately, but it contains the MSRP.

Mobile graphics

Mobile GPUs are a whole different story, so it's good to know that there is a separate list at notebookcheck.net that contains the 3DMark01, 3DMark03, 3DMark05 and 3DMark06 score, which is probably the easiest indicator for performance. While there are numerous restrictions you can apply to the list to filter out specific graphics cards, there is no MSRP or reseller price mentioned. There's also a list available that includes actual FPS rates for popular games for each mobile GPU.

Scroll to the last highlight in irssi

Perhaps you know this situation: You have irssi running in screen and have been away for a few days. You come back and see that you have been highlighted a few hours or maybe even days before. Irssi usually shows you the highlighted line in the server window and it may be something like "daniel: What? Nooo!". Now you're wondering "What the heck was he refering to?", since you don't remember the conversation at that time. Now you would start scrolling back, probably hundreds of lines. When you are connected to your irssi via ssh over a slow line, this may take a second or more per page. It often happens to me that it takes 3 minutes or more to scroll back, just to find out that he mistyped another nick.

I now finally learned about a way to scroll to the highlighted position directly. With the command

/scrollback goto [dd-mm] HH:MM

you can scroll directly to a point in time. And since the timestamp is usually displayed next to the highlight in the server window, it's possible to jump straight to the highlighted position. You can then use

/scrollback end

to go back again to the most recent message in the window.

I was annoyed by that tedious scrolling task for years now, and asked in #irssi every now and then about it, but until today nobody could give me a solution.

Thanks to jink from #irssi on freenode for telling me about /scrollback goto!
