why not try get to know some gamers from your area, some dudes willbe cool enough to share you their spare PC(in the LANS or if they got a spare for sale or not need they might sell it to you) and often it wont be half bad, maybe 2-3 years old...but will still run a BF3 easy, and say...if you knew what you're doing, just check the PSU brand, not not so much the specs, anything over 500Watts is sweet i cud careless for 750-1000w unless you really gonna do dual SLI's crosffires and multi HDDs, (multi like 4-5 PLUS drives) build a good cheap gamer, JUST for gaming, best plan on only 2 drives, a Fast one, and a storage one for apps, drivers, but dont use it for you tubes, and shit you'd slow it right down, and end up trashing the pc...
also check the vid card...if its a REAl cheap shit, stay on it for a while till tou can afford not the BEST, but something quite bit better, look for pipes, clock who fuck cares about Rams, Most are good, 2Gb rams, with slower , less piped gpu is total bullshit but read reviews. decide early on what 'level you want' max out , nah, you be spending $$$$$, not fast mid-level details will be sweet...unless your genre in gaming is all about eye candy, well good luck...(know what foxrac etc are saying...) but each and every gamers 9seasoned ones in particular have diff view, so best and latest is just for those needing big e-cocks...lol forget it
also last thing
if you did get a good 'deal' from local gamers, try suss them in a club, or those regulars at the cybersheds...LANs...better yet, try stick around with those actually organises (or helps organising LANS) they are pretty trust worthy dudes , chances are they are working as techs in day time too...
also last thing
if you spot a good 'was the best' but wel looked after, and not modded mobos, from those descirbed dudes as above,...and see a so and so RAMs...you can aleay get better rams later on, (as a plan to get 350$ PC NOW), then spend couple $100s down the track 100 then another 100 then its sussed... but
FIRT before you do that
CHECK Everything there is to know about that mobo, cpu is running, cache size, (again clocks arent everything) and check the timing,bus limit capability on the RAMS, if yo uKNOW you can go up to DDR3 on a mobo thats now using DDR2, (if it has a DDR3 slots)..etc that sort of thing, or how easy is it to change volts (is that mob got good rep to sligt over volt for good overclock?) that but that's more for advanced users.../gamers...
If i were you,
forget ATI, stick with nivida, GTX something, the best from 2 years ago will KICK this years mid-range ...and sometimes surprised do happens a mid from now is way better...all depends... but usually the BEST from 2 even 3 years back will be still be rocking hard!!!...so the used price for that will prob be slightly more then price of NEW MID NOW...so be prepared about that...but i dunno US market... only giving you ideas...AND if a model seem cheaper than others 'high-end' say a Cross fire single so cheap , chances are it had issues..and unpopular so try be aware of that...
hope this helps
G
rams good names, corsairs, mushkins, OCZ, Gskill
gfx good name, EVGA, BFG, dunno what out there, but you find out...
good cpus, go quads if you can afford it, or a high end duals, forget AMDs unless their quads are cheap and a good batch /cache you have to sort that
mobos, theres always gonna be some favourites...find out what are they, and 'remember them' so that then if you spot those in a cheap deal an as long there is NO issues the board you gotta talk to them,, it could be a great starter, in fact a killer, cuz in gaming esp in LANs, in Most cases, unless your in the BEST gaming Class you dont need all the speed, and gloss, speed for games btu not gloss as details..and gaming is more about skills than specs...
CounterStrike Source still played by many, a fucking good game, so popular it can be played on laptops, and you can still WIN...cuz the game itself was BUILT for LANs not glossy eye-candy and specs show-offs
HDDs pretty cheap,
GFX...cheap now...but dont getb fooled with Cheap with BIG rams...would likiely be SHIT GPU, great for videos but utter shit for games...
ok GOOD LUCK!
