Baptiste Serin came in as the tenth best performer in round four after he earned man of the match against Italy, helping teammate Virimi Vakatawa across the line with a perfectly-timed offload.
The 22-year-old scrum-half has progressed immensely in this year's tournament and will be well worth 12.40 stars if he continues in his current form.
At the other end of the price scale, Owen Farrell tops the table for the best fantasy points average and is predictably a big investment at 16.30 stars.
France's Camille Lopez has been the top points-scorer so far though, so Farrell will only pay off if England manage to secure the Grand Slam in Dublin.
The Wales versus France game may be the most physical of the weekend, so their back rows should perform well on the tackle front.
Louis Picamoles is the obvious choice and scored 67.50 fantasy points in Round Four, but unsurprisingly will set you back 16 stars.
Having helped La Rochelle to the top of the table in the Top 14 before leaving for international duty, Kevin Gourdon has carried his club form into the RBS 6 Nations, collecting 50 fantasy points last weekend.
For Wales, Justin Tipuric has made 58 tackles over the last four games and will live up to his 14.70 stars price tag if he maintains this work rate.
Joe Launchbury was the highest ranking lock last week, bringing home 47 points, and has deservedly been named man of the match twice and has amassed 111 metres.
Alun Wyn Jones also scored well last week - Jones is 14.55 stars and is up against the returning Sébastien Vahaamahina.
A slightly cheaper option in the French pack is Yoann Maestri, who scored a respectable 43 fantasy points last week and comes in at 14 stars.
Cyril Baille ranks in the top five locks, averaging 15.6 fantasy points a game, and will have significantly less impact on your budget than those above him at 10.85 stars.
At hooker, Ken Owens has been quietly enjoying some strong performances for Wales, scoring 29.70 last week but staying cheaper than other high scorers Dylan Hartley and Guilhem Guirado at 11 stars.
For Scotland, Zander Fagerson is one of the cheapest players on offer at 8.85 stars despite continuing in the fine form he displayed for Glasgow earlier in the season and averaging 13.1 fantasy points.
