Singapore dollars is about the same as Australian dollars, which is about AUD$1: USD$0.80.
Which makes that card a very expensive low-end card.
Doesn't change the fact that his system's spec still doesn't meet the requirements for L4D2 no matter what. CPU requirements says minimum is a Core2Duo, and as far as I know, LGA775 motherboards with AGP slots are pretty hard to come by.
I guessed as much. Which means you wouldn't be able to play L4D2 very smoothly, if at all.
Upgrading your graphics card to the best available for the AGP system won't help too much I suspect, even with everything turned way down....
Anything that would plug into your current system would not be value for money; performance/$ would be very low, plus (depending on exactly how old your system is) the fact that you may start to have "aging" problems with your computer. Components like the CPU might have a long life, but motherboard capacitors don't; PSU's have caps which fail with time too; and don't forget HDDs, which can fail even when new are much much more likely to fail after 5 years.
So unless you absolutely cannot wait to upgrade and can't afford anything better, or have some program with will run only on that PC (or some other reason not to change to a whole new PC), I suggest you get a new one.
poor link took a while but I think this was the reference https://www.techspot.com/vb/topic51437.html
Not that we think that @jojodancer you're boasting at all about that new config. Antec 300 case etc. etc.etc. :grinthumb
The best advice we can give you is to upgrade your system as well.
Seeing as most new games, assuming thats what you are gona use it for as well, needs a lot of processing power, upgrade to atleast a core 2 duo. It is alot cheaper to buy new these days than trying to upgrade an old pc.
